The article presents materials on studying distribution
and phytocenotic confinedness of relict steppe species
of Astragalus angarensis. Astragalus angarensis is the
endemic of the Angara region and Yakutia, it is a relict
species. Three small isolated fragments express the
area of species. The largest fragment was found in the
Angara region; the smallest two fragments are
occurred in the valley of the Lena river, in the southwest
Yakutia near Olekminsk and in the central
Yakutia, from Yakutsk to Bulgunnakhtaakh village.
Ecological and geobotanical characteristics of habit
area of Angara Astragalus is given; floristic content of
community is studied. The described desertificated
Krascheninnikovia, Psathyrostachys steppes and also
Festuca, Agropyron, Koeleria and Artemisia
communities with Astragulus angarensis confined to
slope habitats, characterized by poor floristic content
that gives evidence of low competitiveness of this
species
Novoafonskaya cave is located in Abkhazia. It is
equipped for visits in 1975. The cave has permanently
installed lighting. In caves with artificial lighting, a
vegetation of cyanobacteria and algae, bryophytes and
ferns can be found around lamps. The development of
lampenflora is a typical problem for cave management.
We have identified 69 species of phototrophs in
Novoafonskaya cave: Magnoliophyta 2 species,
Pteridophyta 6 species, Bryophyta 11 species,
Cyanobacteria 34 species, Bacillariophyta 9 species,
Ochrophyta 2 species, Chlorophyta 5 species. The
article considers main habitat of lampenflora and gives
their characteristics. We have also revealed
predominance of cyanobacteria in the cave
The article presents the results of the research on the
effect of processing cuttings grapes Moldova and
Bianca by a growth regulator called Stimolant 66f
(Stimolante 66f) on their regenerative properties, the
yield and quality of seedlings. In Moldova grade, we
tested three concentrations of the drug - 0.001; 0.01
and 0.1% and grade Bianca - five - - 0.001; 0.005;
0.01; 0.05 and 0.1%, compared to treatment with IAA
(standard) or without treatment (control). It was found,
that both types of processing cuttings with IAA led to
the inhibition of blooming buds. Application of
Stimolanta to both varieties accelerated blooming
buds, and to the greatest extent on grade Bianca. On
the variety Moldova, the processing cuttings with
heteroauxin and Stimolant at 0.01 and 0.1% had an
inhibitory effect on the growth of shoots, which
survived to the end of the experiment. On the variety
of Bianca, both the IAA and Stimolant at all
concentrations of working solution contributed to a
significant increase the length of the shoots. At grade
Moldova, basal ends of cuttings treatment for 24 hours
in solutions of Stimolanta at 0.01 and 0.1%
concentration had the root-growing ability stimulated,
enhanced the yield and quality of seedlings. In grade
Bianca, better rooting of cuttings with 3 or more roots
was observed in the variant of "Stimolant - 0.05%",
and a greater number of roots were produced in the
version of "Stimolant - 0.1%." In cuttings of varieties
ofMoldova, Stimolant showed better results than the
IAA in optimal concentrations, and grade Bianca had
about the same results
The article presents the results of the research carried
out in 2007-2014. The aim of the study was the
composition of the microflora of the leaf surface of
some plants of the family Grossulariaceae. Based on
these data, the authors distinguish the typical
representatives of the leaf surface microflora. The
authors study the features of isolated strains
interactions
The article presents the results of studying the
growth-stimulating activity of the microorganisms of
the genus Bacillus of leaf surface microflora arboreal
plants in Stavropol. Isolated and identified strains of
epiphytic microorganisms of the genus Bacillus with
the leaf surface of plants: Quercus robur L., Carpinus
caucasica Grossh., Fraxinus excelsior L., Acer
campestre L.. Growth stimulating properties of 43
strains of aerobic spore-forming bacteria (Bacillus
subtilis, Bac. megaterium, Bac. pumilis, Bac. cereus,
Bac. Licheniformis) are researched. Selected strains
are potentially promising in the development of
microbial preparations for plants. A regional
collection of strains of epiphytic organisms was
formed
The authors propose to consider alien invasive species
as new bioresources. These plants form powerful
(usually single-species) thickets in the secondary range
and their size are larger than at the native cenosis. The
territory occupied by invasive species, especially in
disturbed habitats, is quite high, so their possible yield
is very high. The main problem of using alien species
in the pharmacological purposes is the lack of
information about the dynamics of the chemicals
accumulation. Available data on the biochemistry in its
natural habitat is inadaptable for the same taxon in the
secondary range because of significant
microevolutionary changes. In this work we present
the results of phytochemical screening four legume
species, formed invasive populations in the Middle
Russia - Galega orientalis Lam., Lupinus polyphyllus
Lindl., Robinia pseudoacacia L. & Caragana
arborescens Lam. Information about these species as
traditional medicine plants is given. Original data on
the concentration phenolic compounds and biophile
silicon in leaves and inflorescences are presented.
Information on the fractional composition of the
flavonoid complex is done. Taking into consideration
the high adaptability of invasive species, the chemical
analysis of the samples from different ecotypes was
made. It is shown that accumulation of bioactive
agents & biophile silicon isn’t depended on the
environmental conditions. Concentrations of
polyphenolic compounds were at the average level in
comparison with medicinal plants. Thus, the
combination of flavonoid complex with biophile
silicon provides pharmacological significance of
studied species, and justifies the needing the further study of invasive plant species in order to create new
herbal medicines
The flora of Yakutia is rich in medicinal plants. Many
of these plants are not still studied totally. The species
Rhodiola (Crassulaceae) is one of the most popular
family which are widely used by the local population
for therapeutic purposes. Medicals use the rhizome and
roots of Rhodiola rosea as a source of medicinal raw
materials. This means the removal and destruction of
plants. The procurement should be carried out solely
on the basis of plants grown in culture because of the
rarity and few natural reserves of the species. R. rosea
L. passes a full cycle of the sprouts, blossoming and
bearing fruits during the introduction in the conditions
of Central Yakutia. The weather conditions of the year
influence on the rate of development and growth
processes very strong. The experiments determination
of the germination of local reproductions were
negative. The sprouts grow very good. In this case, it is
good possibility of intense vegetative reproduction of
Rhodiola. The evaluation of stability of introduction
may be attributed to the kind of group stability. The
great potential and adaptive capacity of R. rosea
significantly enhances the possibility of growing this
species under conditions of the Central Yakutia. It is
recommended to improve and elaborate of protection
of natural populations and unique plant communities
The article deals with the topical issues of ornamental
woody plants used in street landscaping of Sochi
Central district. It presents the quantitative
composition of these species, numbering 12181
specimens. With the scale, modified for the regional
conditions, we carried out an analysis of the studied
plantations and their state, which revealed that
weakened plants were predominant - 72.48%. Healthy
plants make up over 20%. The lowest number of the
specimen was recorded among the dead plants
(0,26%). The analysis was carried out for all species
according to the state categories. For instance,
structure-forming species selected for further studies,
were analyzed this way, including a large part of plants
that belong to the second category of state (89,04%).
Healthy plants are less than 8% from the total number
of dominant species. The number of dead plants makes
up 0,35%
The article represents the results of the experiment on
biohumate «Vermistar» (which was obtained by vermiculturing)
and its effects on mycological soil composition.
Humic preparations are interesting in the way
of detoxication of soil. When humic compounds are
active, herbicides and pesticide decompose faster and
concentrations of heavy metals are lowered. Adding
humic fertilizers affect the physical properties of water-Soil:
increases capillary and light soil field capacity
(an average of 20-30%) and heavy water permeability,
improves the structure and its water stability, reduced
soil density. It was noted, that low doses of humic fertilizer
contributes to water-stable aggregates, and high
- change the ratio of the structural units in favor of
agronomically valuable fractions. This, in turn, is accompanied
by changes in the humus state, and biological
characteristics of the soil. Moreover, increased
microbial activity was observed in the first year of
application of fertilizers and as an aftereffect. The
maximum total number of microorganisms established
in the initial phases of plant development. The increase
in the number of microorganisms is enhanced and the
enzymatic activity of the soil which in turn increases
the mobility of soil nutrients
A priority direction at the present stage of vegetable
growing development is to obtain high-quality,
environmentally friendly production on the basis of
development and introduction of new technologies of
cultivation. At the same time, it is compulsory to
emphasize the importance of expanding the range of
crops which can vary nutrition of population. Currently
promising direction is search of new high-efficient and
environmentally friendly methods of plant protection.
Biological methods of effect on the plant body acquire
great significance. One of such methods is using grafts.
In a light of new changed conditions, the research on
grafted plants was not conducted in our country
