Flora, vegetation and productivity potential
of the Vladeasa massif
Summary
Chapter I. Introduction. Studies and researches on the
Vladeasa massif were carried out for 20 years consecutively, and a labora-
tory-house was also built for the same purpose (Fig. 3).
Chapter II. Natural conditions. The Vladeasa massif
was formed during a long geological evolution which began before the Pa-
leozoic and lasted up to the Quaternary; it is situated in the north-eas-
tern part of the Romanian Western Carpathians (Munfit Apuseni). The
eastern part which has been studied is of about 300 km2, with a varied
relief (500—1838 m altitudine); it presents a great lithological diversity as :
sandstone of the superior Cretaceous, dacite andesite, dacite grano-porphyry,
dacite andesite intorsions, rhyolite breccia, limestones with crystalline
aspect, crystalline schists, etc.
The relief, as well as the phytocoenotical variability, determined
various soil types. There have been found alluvial soils with associations as :
Alnetum incanae, Agrostetum albae, Festucetum pratensis, etc.; brown earth
mor-like mull, with primary associations of Fagetum carpaticum, Abieto —
Fagetum, after clearing with secondary associations of Festueeto — Agro-
stetum tenuis montanum, Trifolio — Festucetum rubrae, Lolietum perennis,
etc. Festucetum rubrae montanum^ Festueeto — Agrostetum tenuis montanum,
Lolietum perennis, etc. occupied the brown yellow earth. Brown crypto-
podsolie earth, with primary association of Picetum subalpinum, Piceto —
Juniperetum vacciniosum, after clearing populated by Festucetum rubrae
montanum, Festueeto — Nardetum strictae montanum, Nardeto — Vacci-
nietum, Vaccinietum myrtilli, etc. Podsol soils with duff mull, with the
following associations : Piceto — Fagetum carpaticum, Picetum montanum,
after clearing with Sambuceto — Calamagrostetum arundinaceae, Agro-
stetum tenuis biharicum, Festucetum rubrae montanum, Nardetum strictae
montanum, etc. Podsol soils with secondary lying fallow, with the following
associations : Agrostetum tenuis montanum, Festucetum rubrae montanum,
Festueeto — Nardetum strictae montanum, Festueeto — Alchemilletum vul-
garis, Trifolio — Festucetum rubrae, etc. Podsolic high mountain brown
earth, with the associations : Picetum subalpinum, Piceto — Juniperetum
vacciniosum, Nardeto — Vaccinietum, Vaccinietum myrtilli, etc. Humus sili-
cate soil (subalpine Ranker) with the associations : Nardetum subalpinum,

pine brown earth, with Juniperetum nanae, Festucetum rubrae subalpinum,
Festucetum agrostetosum subalpinum, Nardetum strictae subalpinum, etc.
Dark brown acid cryptopodsolic soils, with raw humus acid duff mull,
with the following associations : Pinetum mughi, Juniperetum nanae.
Chapter III. Studies on soil biology. The researches
included in this chapter lead to the following conclusions :
— as the phytocoenoses are in more advanced stages towards dis-
climax or climax, the amount of organic matter deposited in, or on, the
soil is higher and higher ;
— parallel to the evolution of the phytocoenose succession a slower
decomposition of the dead organic matter could be observed ;
— according to the various succession stages, there is a decrease in
the nitrogen content of the dead organic matter in the phytocoenoses and
an increase of cellulose content ;
— the soil aeration decreases parallel to the age of association and
to the evolution of the phytocoenoses ; the intensity of pedobiological pro-
cesses decreases implicitly ;
— in similar pH condition various associations are developing, de-
pending on the soil nutrition regime and on its constancy ;
— during the nine years of consecutive application of the various
mineral fertilizers, significant pH modifications were induced in none of
the studied associations ;
— each association has a specific humus content increasing accord-
ing to the succession phase towards disclimax or climax ;
— the number of the soil bacteria and surface biomass show parallel
curves, with some unavoidable deviations (Figs 6 and 7) ;
— the amelioration of the trophic regime induces a more intense
relationship between the higher green plants and the soil microorganisms
which also increase the biomass ;
— with artieifial soil heating, by burning the woody material (100 —
150°C) soluble phosphate increases and maintains its high values up to
8—10 years, nitrogen 4 — 6 years ; the number of bacteria increases very
much, as a result of a favourable modification of the soil physico-chemical
conditions ;
— there is a succession of several associations and subassociations
on the same soil type, according to the edaphobiologic conditions required
by the various coenotaxa.
Chapter IV. Studies on Flora. These studies and researches
had a successive and in some biotopes also a stationary character, similar
to vegetation.
The phanerogams of the Yladeasa massif belong to 83 families,
and 367 genera being 1010 species, 23 subspecies, 53 varieties and 22 forms.
The following new taxa are described : Potentilla argentes var. trifoliolobata,
Gentiana austriaca var. simplex, G. praeeox var. depauperata f. filipii
308
SUMMARY
and Pedicularis limnogena f. alba. 99 species are rare or very rare in the
Romanian Western Carpathians and 33 are new records for the same mount-
ains : Sequoia giganteia (planted), Bianthus tenuifolius, Heliospermum
quatrifidium, Silene armeria var. lituanica, Batrachium trichophyllum, Fu-
maria rostellata, Alyssum desertorum, Trifolium bertrandi, Heracleum pal-
malum, Hesperis moniliformis, Tozzia alpina, Qentiana austriaca, G. wn-
culosa, Asperulla tenella, A. capitata, Galius flaveseens, Leontodon danu-
bialis, Narcisus poeticus, Allium vistorialis, Carex repens, C. bigelovi, C.
rupestris are some of these. The Euro-Asiatic elements prevail — 33.50%;
the Mediterranean elements present a great phytogeographical importance
— 4.38%; Continental —3.23%, Balkanic-Illyric — 2.47%; Pontic-
Mediterranean — 1.59 % ; Dacian-Balkanic — 1.28% ; and endemic —
1.92%. The thermophilic Mediterranean Carpathian-Balkanic and Alpine-
Central European elements have a special significance. Among these relicts
should be mentioned Syringa josikaea, Hedrajanthus kitaibellii and Pedi-
cularis limnogena, survivors of the glacial period.
Ecological and fodder indexes are given for 220 grassland species,
namely : humidity with 7 degrees, temperature with 6 degrees, soil reaction
with 6 degrees and fodder value with 8 degrees (Table 11).
Chapter 7. Vegetation study. Associations and sub-associa-
tions are described based on the synthetical table of ten records for the
coenotaxa already described, or 51 records for those which are newly de-
scribed. Fifty-five associations are recorded based on tables of characteris-
tic species, while 25 associations of limited spreading are mentioned simply
as existent. The characteristic-indicator species were taken into considera-
tion in defining the association, special attention being paid to those with
high constancy. The associations were established on phytocoenoses having
the same physionomic, floristic and ecological patterns, as well as with
the same dynamics showing similar reactions when anthropic factors
involved.
There have been identified 14 classes, 20 orders, 28 alliances, 4 sub-
alliances, 76 associations, 7 sub-associations and several facies in the stu-
died area. The following have not yet been described : Calthetum lactae
Krajina 1933 biharicum ass., reg., Nardo — V accinietum, Piceto — Juni-
peretum vacciniosum, Holcetum lanati Issler 1936, biharicum ass. reg., Sam-
buco — Calamagrostetum arundinaceae, Fesiuceto (rubrae) — Callunetun vul-
garis■, Festucetum (rubrae) — agrostidetcsum subalpinum, Fpilcbietum luzu-
letosum, Calamagrostetum —agrcsteicsum, Festuceium — (rubrae) — cytiseto-
sumnigricantis.
Chapter VI. Dynamics of vegetation influenced by an-
thropic and phyto-biotic factors. The evolution of vegetation was followed
during 34 years in sites where the spruce-fir (Picea excelsa) was removed,
which allowed to establish syndynamic and synecological statements :
— characteristic species of Picea abies clearings occur oniy in sites
without pasture;
— there is an increase in species number in the first 7 — 10 years,
followed by a decrease, ending in phytocoenoses of Nardus.
309
SUMMARY
— there is an inverse ratio between the mineral content of the soil
and the number of species of the vegetation;
— due to the pasture and animal excrements, the Agrostis tenuis stage
is about 10 — 20 years, that of Festuca rubra 20 — 50 years;
— dicotyledons dominate the first stages, followed afterwards by
the massive occurrence of monocotyledons, the dynamic equilibrium being
settled when the land is equally occupied by both groups;
— the succession of these stages is avoided by oversowings ;
Vegetation dynamics was followed during 19 years where Juniperus
sibirica was cleared, the following important conclusions being revealed
(Fig. 16) :
— in the first stage, various dicotyledons dominate while in the
second one monocotyledon, with Festuca rubra and Agrostis tenuis prevailing.
— when fertilizers are added, Festuca rubra and Agrostis tenuis
(aftre 5 — 10 years) mostly replaced by Nardus stricta associated with
species Vactinium)
— Vactinium and the moss species occurring under Juniperus
sibirica are significantly thinned out, with complete light conditions or
by the passing of animals;
— the curve of the species number in the succession is very similar
to that shown by cleared Ficea abies stands.
The stands with artificially heated soil exhibit three vegeta-
tional stages : the first with predominance of dicotyledons (Campanula
abietina, Viola declinata, etc.); the second with monotyledons, mostly Poa
annua; the third stage is in dynamic equilibrium with both groups (Fig.
17). The above-mentioned stages may be eliminated by sowing Festuca
rubra, Agrostis tenuis, Trifolium repens, T. hybridum, etc. The sowed spe-
cies are maintained for 20 years in the phytocoenoses which are converted
then into the zonal vegetation type.
The following conclusions were drawn, based on biotopes broken
ground, fertilized and sown with adequate species (Figs 18 and 19) :
— the edapho-biological equilibrium is deeply modified by a mere
breaking ground and it is markedly reflected on the structure of the
renewed vegetation;
— sowing and fertilizing induce a compact vegetable covering from
its first year, the sown species being dominant;
—sooner or later the vegetation composition converges towards the
zonal type of herbaceous and afterwards woody vegetation.
Studies on the vegetation dynamics of the biotopes with ameliorated
trophical regime pointed out the following :
— as regards fodder, important phytocoenotical modifications take
place in all herbaceous associations ;
— concerning the phytocenoses of Nardus the competition takes
place initially between Nardus stricta and Festuca rubra; meanwhile the
second species, considered as the winner in the first part of this competi-
tion, looses it in the second part for the benefit of Agrostis tenuis;
310
SUMMARY
— the phenomenon is reversible, if the fertilization is not regularly
repeated ;
— if calcium is applied in corresponding doses, its effect on Nardus
will be visible after 3 — 5 years, the multiplication of Festuca rubra being
evident ;
— the masses and some phanerogams (Potentilla aurea, Campanula
abietina, etc.) cannot tolerate the amelioration and diminish to their com-
plete disapearance.
The vegetation dynamics affected by its utilization manner, followed
during 8 years on end, revealed the following phytocoenotical aspects :
— when the grassland is in its younger stage — as regards its dyna-
mics in time — there could be observed more evident differentiations in
the vegetation structure, by its utilization as meadow on the one hand, or
pasture on the other ;
— the time necessary to notify quantitative and qualitative changes
in the vegetation is determined by the grassland type and by its age ;
— on one and the same grassland, the grazing induces more stressed
and earlier modifications than those induced by mowing ;
— fertilization intensifies the positive effect of the utilization of
grasslands as meadows — in comparison with the pasture in the sense that
Nardus stricta and other light-loving species decrease in a shorter time ;
— in order to maintain a phytocoenotical equilibrium as productive
as possible, an alternative utilization of meadows and grazing lands is
suggested.
The experiments performed in order to reveal the modifications of the
phytomedium under anthropic influence suggested the following conclusions :
— any intervention in the soil trophic processes will implicitly modify
the metabiotical processes as in the case of Hieracium piosella, where the
effect of toxins was annihilated ;
— the synergism created the conditions of a mutual support, reflect-
ed in positive biochemical modifications of Trifolium pratense and Festuca
pratensis, Cucumis sativum and Trifolium arvense ;
— the composition, structure and the age of phytocoenoses determine
certain differentiations within the thermic regime, soil carbon dioxide, in
humus, in the number of offshoots on m2, in the biomass of the phyto-
coenoses, etc. ;
— when the secondary vegetation is nearer to disclimax the ecological
conditions are less favourable to the installing of the climax vegetation ;
— the thickening of. the grass layer reduces soil and air exchanges,
thus also inducing the diminution of edapho-biological processes, reflected
in the biomass decrease.
Chapter VII. Experiments on the productivity po-
tential of grasslands.
Experiments were carried out at 500 — 1823 m altitude, in 19 stands,
with 152 variants.
311
SUMMARY
From these data, the basic important conclusions are summarized as
follows :
— the biomass is mostly affected by the interrelation complex of
biotic and abiotic factors, and as such its curves are not parallel to those of
the climatic factors;
— the modification of an ecological factor, as the soil aeration, or
its nitrogen content, etc., induces changes in the physical, chemical and
biological conditions of the soil, which directly affect the amount and
quality of the biomass;
— modifications in the biological equilibrium of a given biotope, pro-
duced by anthropic causes, are reflected in the composition and structure
of the vegetation, the whole having a reversible character, whence the neces-
sity of our repeated intervention;
— the same cause will not always induce the same effect, because
various factors are interfering at random; as such the productivity
cannot be entirely predictable, when man is interfered;
— some biotopes — after 9 years of consecutive treatment with fer-
tilizers — presented a decreasing curve (especially in the second and the
third year) (Figs 20, 23 and 24);
— one cannot expect a rule between the biomass and based on the
trophic status as well as climatic conditions only;
— the biomass is mostly affected by the trophic states and the com-
position of the grassland;
— as the graminaceae are more massively prevailing and the plants
number on a surface unit is grater, a higher productivity can be expected
by the montane or subalpine grasslands fertilizing;
— the application of fertilizers at irregular time intervals and in va-
riable doses may be efficient;
— pedobiological processes induced by the first treatments will be
latently kept for some years, especially the organic fertilizers or the repeat-
ed moderate doses of nitrogen-phosphorus which will produce an increased
biomass;
— Nardus strieta will be entirely controlled by the simultaneous soil
aeration with its breaking ground;
— evidence is made of a superposition of the negative effects of
the exposure and slope with the altitude negative effects, in productivity
limitation and in fertilizers efficiency;
— the northern exposure induces a biomass depression, parallel to
the growth of slopes (Fig. 29);
— as the altitude and the slope are increasing, biomass differentia-
tions betwnee the southern and northern exposures are more evident
(Fig. 29);
— there is no strict parallelism between the biomass and altitude,
which will be more strikingly made evident over 1200 m;
— soil productivity decreases on altitudes, determined by the slope
and the exposure, but inversions may also be observed (Fig. 30);
312
SUMMARY
Chapter VIII. Aspects concerning forest produc-
tivity potential. Fagetum carpaticum registers at 600 m altitude
— 6.16 mc/ha/annual, and 4.60 mc/ha/ann. at 1000 — 1200; Picetum
montanum recorded 8.01 mc/ha/ann. at 1130— 1320 m; Picetum subalpi-
num 2.00 mc/ha/ann at 1380 — 1600 m altitude.
Chapter IX. Researches on the chemical com-
position of the vegetable mass of some phyto-
coenoses and of more species. The conclusions of these
researches are summarized as follows;
— animals consume the grass of fertilized variants in the following
order of preference : organic-manure-fertilized variant, jSTP variant and
N variant;
— the greatest protein amount on a surface unit will be obtained by
NP and K treatments ; this is another reason for recommending their prac-
tical use;
— exclusive nitrogen treatment stimulates indirectly the solubiliza-
tion of the soil mineral elements, necessary to plant nutrition, as it results
from biochemical analyses;
— KK treatment most intensely stimulates (on the Vladeasa massif)
protein synthetizing, as compared to other variants;
— consequently to the stimulation of the phytosynthetical process —
more intense than mineral element absorption — the ash content of some
treated variants is smaller than in the untreated controls.
— calcium has a positive contribution in the pedobiologic processes,
as reflected in the increased content of plants mineral elements;
— the phytocoenoses development environment induces various
directions in the species metabolism of each phytocoenosis in part.
At hay harvesting, among others, phenological stages determine a
very varied chemical content of the species.

Flora, vegetation and productivity potential
of the Vladeasa massif
Summary
Chapter I. Introduction. Studies and researches on the
Vladeasa massif were carried out for 20 years consecutively, and a labora-
tory-house was also built for the same purpose (Fig. 3).
Chapter II. Natural conditions. The Vladeasa massif
was formed during a long geological evolution which began before the Pa-
leozoic and lasted up to the Quaternary; it is situated in the north-eas-
tern part of the Romanian Western Carpathians (Munfit Apuseni). The
eastern part which has been studied is of about 300 km2, with a varied
relief (500—1838 m altitudine); it presents a great lithological diversity as :
sandstone of the superior Cretaceous, dacite andesite, dacite grano-porphyry,
dacite andesite intorsions, rhyolite breccia, limestones with crystalline
aspect, crystalline schists, etc.
The relief, as well as the phytocoenotical variability, determined
various soil types. There have been found alluvial soils with associations as :
Alnetum incanae, Agrostetum albae, Festucetum pratensis, etc.; brown earth
mor-like mull, with primary associations of Fagetum carpaticum, Abieto —
Fagetum, after clearing with secondary associations of Festueeto — Agro-
stetum tenuis montanum, Trifolio — Festucetum rubrae, Lolietum perennis,
etc. Festucetum rubrae montanum^ Festueeto — Agrostetum tenuis montanum,
Lolietum perennis, etc. occupied the brown yellow earth. Brown crypto-
podsolie earth, with primary association of Picetum subalpinum, Piceto —
Juniperetum vacciniosum, after clearing populated by Festucetum rubrae
montanum, Festueeto — Nardetum strictae montanum, Nardeto — Vacci-
nietum, Vaccinietum myrtilli, etc. Podsol soils with duff mull, with the
following associations : Piceto — Fagetum carpaticum, Picetum montanum,
after clearing with Sambuceto — Calamagrostetum arundinaceae, Agro-
stetum tenuis biharicum, Festucetum rubrae montanum, Nardetum strictae
montanum, etc. Podsol soils with secondary lying fallow, with the following
associations : Agrostetum tenuis montanum, Festucetum rubrae montanum,
Festueeto — Nardetum strictae montanum, Festueeto — Alchemilletum vul-
garis, Trifolio — Festucetum rubrae, etc. Podsolic high mountain brown
earth, with the associations : Picetum subalpinum, Piceto — Juniperetum
vacciniosum, Nardeto — Vaccinietum, Vaccinietum myrtilli, etc. Humus sili-
cate soil (subalpine Ranker) with the associations : Nardetum subalpinum,
307
SUMMARY
Festucetum rubrae subalpinum, Potentillo — Festucetum ovinaet Cetrarieto —
Vaccinietum uliginosi, Nardo — Vaccinietum, etc. Cryptopodsolic subal-
pine brown earth, with Juniperetum nanae, Festucetum rubrae subalpinum,
Festucetum agrostetosum subalpinum, Nardetum strictae subalpinum, etc.
Dark brown acid cryptopodsolic soils, with raw humus acid duff mull,
with the following associations : Pinetum mughi, Juniperetum nanae.
Chapter III. Studies on soil biology. The researches
included in this chapter lead to the following conclusions :
— as the phytocoenoses are in more advanced stages towards dis-
climax or climax, the amount of organic matter deposited in, or on, the
soil is higher and higher ;
— parallel to the evolution of the phytocoenose succession a slower
decomposition of the dead organic matter could be observed ;
— according to the various succession stages, there is a decrease in
the nitrogen content of the dead organic matter in the phytocoenoses and
an increase of cellulose content ;
— the soil aeration decreases parallel to the age of association and
to the evolution of the phytocoenoses ; the intensity of pedobiological pro-
cesses decreases implicitly ;
— in similar pH condition various associations are developing, de-
pending on the soil nutrition regime and on its constancy ;
— during the nine years of consecutive application of the various
mineral fertilizers, significant pH modifications were induced in none of
the studied associations ;
— each association has a specific humus content increasing accord-
ing to the succession phase towards disclimax or climax ;
— the number of the soil bacteria and surface biomass show parallel
curves, with some unavoidable deviations (Figs 6 and 7) ;
— the amelioration of the trophic regime induces a more intense
relationship between the higher green plants and the soil microorganisms
which also increase the biomass ;
— with artieifial soil heating, by burning the woody material (100 —
150°C) soluble phosphate increases and maintains its high values up to
8—10 years, nitrogen 4 — 6 years ; the number of bacteria increases very
much, as a result of a favourable modification of the soil physico-chemical
conditions ;
— there is a succession of several associations and subassociations
on the same soil type, according to the edaphobiologic conditions required
by the various coenotaxa.
Chapter IV. Studies on Flora. These studies and researches
had a successive and in some biotopes also a stationary character, similar
to vegetation.
The phanerogams of the Yladeasa massif belong to 83 families,
and 367 genera being 1010 species, 23 subspecies, 53 varieties and 22 forms.
The following new taxa are described : Potentilla argentes var. trifoliolobata,
Gentiana austriaca var. simplex, G. praeeox var. depauperata f. filipii
308
SUMMARY
and Pedicularis limnogena f. alba. 99 species are rare or very rare in the
Romanian Western Carpathians and 33 are new records for the same mount-
ains : Sequoia giganteia (planted), Bianthus tenuifolius, Heliospermum
quatrifidium, Silene armeria var. lituanica, Batrachium trichophyllum, Fu-
maria rostellata, Alyssum desertorum, Trifolium bertrandi, Heracleum pal-
malum, Hesperis moniliformis, Tozzia alpina, Qentiana austriaca, G. wn-
culosa, Asperulla tenella, A. capitata, Galius flaveseens, Leontodon danu-
bialis, Narcisus poeticus, Allium vistorialis, Carex repens, C. bigelovi, C.
rupestris are some of these. The Euro-Asiatic elements prevail — 33.50%;
the Mediterranean elements present a great phytogeographical importance
— 4.38%; Continental —3.23%, Balkanic-Illyric — 2.47%; Pontic-
Mediterranean — 1.59 % ; Dacian-Balkanic — 1.28% ; and endemic —
1.92%. The thermophilic Mediterranean Carpathian-Balkanic and Alpine-
Central European elements have a special significance. Among these relicts
should be mentioned Syringa josikaea, Hedrajanthus kitaibellii and Pedi-
cularis limnogena, survivors of the glacial period.
Ecological and fodder indexes are given for 220 grassland species,
namely : humidity with 7 degrees, temperature with 6 degrees, soil reaction
with 6 degrees and fodder value with 8 degrees (Table 11).
Chapter 7. Vegetation study. Associations and sub-associa-
tions are described based on the synthetical table of ten records for the
coenotaxa already described, or 51 records for those which are newly de-
scribed. Fifty-five associations are recorded based on tables of characteris-
tic species, while 25 associations of limited spreading are mentioned simply
as existent. The characteristic-indicator species were taken into considera-
tion in defining the association, special attention being paid to those with
high constancy. The associations were established on phytocoenoses having
the same physionomic, floristic and ecological patterns, as well as with
the same dynamics showing similar reactions when anthropic factors
involved.
There have been identified 14 classes, 20 orders, 28 alliances, 4 sub-
alliances, 76 associations, 7 sub-associations and several facies in the stu-
died area. The following have not yet been described : Calthetum lactae
Krajina 1933 biharicum ass., reg., Nardo — V accinietum, Piceto — Juni-

Chapter VI. Dynamics of vegetation influenced by an-
thropic and phyto-biotic factors. The evolution of vegetation was followed
during 34 years in sites where the spruce-fir (Picea excelsa) was removed,
which allowed to establish syndynamic and synecological statements :
— characteristic species of Picea abies clearings occur oniy in sites
without pasture;
— there is an increase in species number in the first 7 — 10 years,
followed by a decrease, ending in phytocoenoses of Nardus.
309
SUMMARY
— there is an inverse ratio between the mineral content of the soil
and the number of species of the vegetation;
— due to the pasture and animal excrements, the Agrostis tenuis stage
is about 10 — 20 years, that of Festuca rubra 20 — 50 years;
— dicotyledons dominate the first stages, followed afterwards by
the massive occurrence of monocotyledons, the dynamic equilibrium being
settled when the land is equally occupied by both groups;
— the succession of these stages is avoided by oversowings ;
Vegetation dynamics was followed during 19 years where Juniperus
sibirica was cleared, the following important conclusions being revealed
(Fig. 16) :
— in the first stage, various dicotyledons dominate while in the
second one monocotyledon, with Festuca rubra and Agrostis tenuis prevailing.
— when fertilizers are added, Festuca rubra and Agrostis tenuis
(aftre 5 — 10 years) mostly replaced by Nardus stricta associated with
species Vactinium)
— Vactinium and the moss species occurring under Juniperus
sibirica are significantly thinned out, with complete light conditions or
by the passing of animals;
— the curve of the species number in the succession is very similar
to that shown by cleared Ficea abies stands.
The stands with artificially heated soil exhibit three vegeta-
tional stages : the first with predominance of dicotyledons (Campanula
abietina, Viola declinata, etc.); the second with monotyledons, mostly Poa
annua; the third stage is in dynamic equilibrium with both groups (Fig.
17). The above-mentioned stages may be eliminated by sowing Festuca
rubra, Agrostis tenuis, Trifolium repens, T. hybridum, etc. The sowed spe-
cies are maintained for 20 years in the phytocoenoses which are converted
then into the zonal vegetation type.
The following conclusions were drawn, based on biotopes broken
ground, fertilized and sown with adequate species (Figs 18 and 19) :
— the edapho-biological equilibrium is deeply modified by a mere
breaking ground and it is markedly reflected on the structure of the
renewed vegetation;
— sowing and fertilizing induce a compact vegetable covering from
its first year, the sown species being dominant;
—sooner or later the vegetation composition converges towards the
zonal type of herbaceous and afterwards woody vegetation.
Studies on the vegetation dynamics of the biotopes with ameliorated
trophical regime pointed out the following :
— as regards fodder, important phytocoenotical modifications take
place in all herbaceous associations ;
— concerning the phytocenoses of Nardus the competition takes
place initially between Nardus stricta and Festuca rubra; meanwhile the
second species, considered as the winner in the first part of this competi-
tion, looses it in the second part for the benefit of Agrostis tenuis;
310
SUMMARY
— the phenomenon is reversible, if the fertilization is not regularly
repeated ;
— if calcium is applied in corresponding doses, its effect on Nardus
will be visible after 3 — 5 years, the multiplication of Festuca rubra being
evident ;
— the masses and some phanerogams (Potentilla aurea, Campanula
abietina, etc.) cannot tolerate the amelioration and diminish to their com-
plete disapearance.
The vegetation dynamics affected by its utilization manner, followed
during 8 years on end, revealed the following phytocoenotical aspects :
— when the grassland is in its younger stage — as regards its dyna-
mics in time — there could be observed more evident differentiations in
the vegetation structure, by its utilization as meadow on the one hand, or
pasture on the other ;
— the time necessary to notify quantitative and qualitative changes
in the vegetation is determined by the grassland type and by its age ;
— on one and the same grassland, the grazing induces more stressed
and earlier modifications than those induced by mowing ;
— fertilization intensifies the positive effect of the utilization of
grasslands as meadows — in comparison with the pasture in the sense that
Nardus stricta and other light-loving species decrease in a shorter time ;
— in order to maintain a phytocoenotical equilibrium as productive
as possible, an alternative utilization of meadows and grazing lands is
suggested.
The experiments performed in order to reveal the modifications of the
phytomedium under anthropic influence suggested the following conclusions :
— any intervention in the soil trophic processes will implicitly modify
the metabiotical processes as in the case of Hieracium piosella, where the
effect of toxins was annihilated ;
— the synergism created the conditions of a mutual support, reflect-
ed in positive biochemical modifications of Trifolium pratense and Festuca
pratensis, Cucumis sativum and Trifolium arvense ;
— the composition, structure and the age of phytocoenoses determine
certain differentiations within the thermic regime, soil carbon dioxide, in
humus, in the number of offshoots on m2, in the biomass of the phyto-
coenoses, etc. ;
— when the secondary vegetation is nearer to disclimax the ecological
conditions are less favourable to the installing of the climax vegetation ;
— the thickening of. the grass layer reduces soil and air exchanges,
thus also inducing the diminution of edapho-biological processes, reflected
in the biomass decrease.
Chapter VII. Experiments on the productivity po-
tential of grasslands.
Experiments were carried out at 500 — 1823 m altitude, in 19 stands,
with 152 variants.
311
SUMMARY
From these data, the basic important conclusions are summarized as
follows :
— the biomass is mostly affected by the interrelation complex of
biotic and abiotic factors, and as such its curves are not parallel to those of
the climatic factors;
— the modification of an ecological factor, as the soil aeration, or
its nitrogen content, etc., induces changes in the physical, chemical and
biological conditions of the soil, which directly affect the amount and
quality of the biomass;
— modifications in the biological equilibrium of a given biotope, pro-
duced by anthropic causes, are reflected in the composition and structure
of the vegetation, the whole having a reversible character, whence the neces-
sity of our repeated intervention;
— the same cause will not always induce the same effect, because
various factors are interfering at random; as such the productivity
cannot be entirely predictable, when man is interfered;
— some biotopes — after 9 years of consecutive treatment with fer-
tilizers — presented a decreasing curve (especially in the second and the
third year) (Figs 20, 23 and 24);
— one cannot expect a rule between the biomass and based on the
trophic status as well as climatic conditions only;
— the biomass is mostly affected by the trophic states and the com-
position of the grassland;
— as the graminaceae are more massively prevailing and the plants
number on a surface unit is grater, a higher productivity can be expected
by the montane or subalpine grasslands fertilizing;
— the application of fertilizers at irregular time intervals and in va-
riable doses may be efficient;
— pedobiological processes induced by the first treatments will be
latently kept for some years, especially the organic fertilizers or the repeat-
ed moderate doses of nitrogen-phosphorus which will produce an increased
biomass;
— Nardus strieta will be entirely controlled by the simultaneous soil
aeration with its breaking ground;
— evidence is made of a superposition of the negative effects of
the exposure and slope with the altitude negative effects, in productivity
limitation and in fertilizers efficiency;
— the northern exposure induces a biomass depression, parallel to
the growth of slopes (Fig. 29);
— as the altitude and the slope are increasing, biomass differentia-
tions betwnee the southern and northern exposures are more evident
(Fig. 29);
— there is no strict parallelism between the biomass and altitude,
which will be more strikingly made evident over 1200 m;
— soil productivity decreases on altitudes, determined by the slope
and the exposure, but inversions may also be observed (Fig. 30);
312
SUMMARY
Chapter VIII. Aspects concerning forest produc-
tivity potential. Fagetum carpaticum registers at 600 m altitude
— 6.16 mc/ha/annual, and 4.60 mc/ha/ann. at 1000 — 1200; Picetum
montanum recorded 8.01 mc/ha/ann. at 1130— 1320 m; Picetum subalpi-
num 2.00 mc/ha/ann at 1380 — 1600 m altitude.
Chapter IX. Researches on the chemical com-
position of the vegetable mass of some phyto-
coenoses and of more species. The conclusions of these
researches are summarized as follows;
— animals consume the grass of fertilized variants in the following
order of preference : organic-manure-fertilized variant, jSTP variant and
N variant;
— the greatest protein amount on a surface unit will be obtained by
NP and K treatments ; this is another reason for recommending their prac-
tical use;
— exclusive nitrogen treatment stimulates indirectly the solubiliza-
tion of the soil mineral elements, necessary to plant nutrition, as it results
from biochemical analyses;
— KK treatment most intensely stimulates (on the Vladeasa massif)
protein synthetizing, as compared to other variants;
— consequently to the stimulation of the phytosynthetical process —
more intense than mineral element absorption — the ash content of some
treated variants is smaller than in the untreated controls.
— calcium has a positive contribution in the pedobiologic processes,
as reflected in the increased content of plants mineral elements;
— the phytocoenoses development environment induces various
directions in the species metabolism of each phytocoenosis in part.
At hay harvesting, among others, phenological stages determine a
very varied chemical content of the species.
