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 reveals historical aspect of the Donets
Ridge petrophytic vegetation study. The stages of
formation of concepts and terms in the typology of
vegetation of the rocky outcrops of the steppe zone
The work presents the results of the scientific research in
the Taman Peninsula soil properties. We carry out the
historic review of the studies in the Taman Peninsula
soils, and its geological structure. We present
morphological characteristics of the soil profile for the
southern, calcareous, ultra heavy loam chernozem
developed from the loessial loams and forming genetic
horizons. The studies of the humus content in the soils
show the associations between its percentage and the
type and intensity of the agricultural use. Studies of the
soils structure and composition demonstrate marked
aggravation of the soils physical properties caused by
grape growing. The best results of the particle size
analysis have been achieved for the woodland soils. In
woodlands, after their establishment, the soils under the
grass and crown layers develop free of the
anthropogenic impact. We register self-supporting
growth of organic matter and natural processes of soil
fertility recovery; therefore, such soils are characterized
with a greater content of organic matter as compared to
the soils under grape plantings cultivated in the
monoculture regime. Reduced soil organic matter
(humus) content in vineyards results from the disturbed
biological interchange of the matter and increased
anthropogenic impact causing erosion processes
In the populations of Taxus baccata of Foothills and
Inside Mountain Dagestan, we have studied intra- and
interpopulation variability of morphological characters
of yew berry. The article has a contribution of
interpopulation differences in the feature of "diameter
of funnel" with the highest rates in Buynaksk
population and dependency of the form of yew berry
from this feature. According to the results of
discriminant analysis, we have revealed a distinction in
populations on this basis, although the classification
matrix has not given 100% of the forecast for any of
them. It is found, that the seeds of Khunzah population
have relatively large dimensions and yew berry has
more flattened shape compared to piedmont
populations, while the differences in populations based
on seeds are more pronounced than based on yew
berry at low volatility of the characteristics of the first
indicators. It is shown, that the characteristics of seeds
and yew berry of Khunzakh population indicate the
presence of certain genetic differences between
populations inside mountain and foothills, and that the
higher dissemination activity of first population is
aimed at self-preservation, due to the less favorable
conditions for the species. It is expected that the low
variability of the average values for yew berries of
cypress characteristics indicates the stability of the soil
and climatic conditions of its habitats
The article is concerned with the features of Lavandula’s
angustifolia vegetative propagation with methods of the
propagation by herbaceous cuttings and of the annual
woody cutting. The dependence of Lavandula’s varieties
Sineva and Vdala rooting of cutting and the cutting grafting
period and the age of the mother plantation was
established. In the fixed years, the rooting rate of cuttings is
58-67%. The maximum annual hardwood cuttings rooting
was observed from the fifth to the seventh year of the
cuttings’ workpiece (75-77%). The highest rooting rate of
green cuttings belonging to Vdala sort (80%) is observed in
the 3-4th years of use the mother plantation. The best result
for rooting rate by the annual woody cutting showed
Lavandula’s mother plantation, which belongs to Vdala
sort and was being cultivated from 3rd to 6th year. The
rooting of Lavandula’s angustifolia cuttings depends on
weather conditions; during drought years the rooting of
green cuttings is considerably reduced. During Lavandula’s
rooting cuttings it is necessary to take into account the
biological characteristics of each variety
The study was performed to genotype some
commercial wine yeast strains using the assay of Interdelta
genomic sequences. Experimental parameters of

In this article, we have presented a number of modeling experiments to investigate the chemical pollution of brown calcareous soil. It assesses the stability of brown calcareous soil of a nature reserve called Utrish to contamination with heavy metals in biological parameters. Pollution of brown calcareous soil with Cr, Cu, Ni, Pb and oil causes a significant reduction in biological parameters. The degree of reduction depends on the nature of the contaminant and its concentration in the soil. The study showed that the indicators used in the biological condition of the soil, could be recommended for use for diagnosis, monitoring, and regulation of chemical pollution of brown soil. According to the degree of resistance to chemical contamination, the brown soils of Russia form the following series: typical brown - brown carbonate - brown leached
We have investigated the influence of nickel oxide in
the amount 100, 1000 mg/kg of the soil (1, 10 MPC),
combined with the influence of variation magnetic field
with induction of 50, 100 and 650 μT power frequency
of 50 Hz on the enzyme activity and phytotoxity of the
southern chernozem. We have established significant
reduction of enzyme activity of catalase and length of
roots after the influence of the variation of magnetic
fields. Pollution by nickel as an independent factor
caused stimulation of enzyme activity of a
dehydrogenaze and length of roots of radish. The
greatest inhibition of the activity of all indicators was
observed at joint influence of magnetic fields and
pollution by nickel of concentration of 1 maximum
permissible concentration (1 MPC). Enzyme activity of
dehydrogenaze was significantly stimulated (p
Large agricultural load on the steppe landscapes
leads to the transformation of ecosystems and effect
on all their components. Transformation of lands into
laylands leads to a gradual restoration of
anthropogenically disturbed steppe ecosystems.
Studies that focus on the research of comprehensive
processes in the territory of laylands are extremely
relevant today. Herpetobiont fauna is one of the
important characteristics of ecology and biology of
soils. Herpetobiont Coleoptera can serve as
indicators in the study of processes occurring in
postagrogenic soils.The article presents the results of
the study of changes in mesofauna, composition and
structure of complexes of the gerpetobiont
Coleoptera of ordinary black soils in natural
succession series of different-age laylands. We also
evaluated the degree of faunistic similarity of plots
of laylands and allocated dominant species.
Carabidae and Tenebrionidae are the basis of
complex Coleoptera in the investigated laylands. The
article shows that such indicators as the number of
individuals, species, families of beetles and their
dynamic density are depended on the age of the
layland. In addition, the indices of biodiversity
(Margalef and Shannon) and dominance (Simpson)
are also connected with the age of plots of laylands
The article presents the results of laboratory
modeling of gleyisation and its effect on the
biological properties of soils with stagnant regime in
ordinary black soils. Gleyisation is a complex
biochemical process that occurs under oxygen
reduction conditions. Anaerobic microorganisms, the
presence of organic substances, and the constant or
prolonged waterlogging of individual horizons or the
entire soil profile promote gleyisation. Model
experiments revealed that gleyisation increase the
total number of bacteria and suppresses number of
actinomycetes, micromycetes and growth of fungal
mycelium. Gleyisation decreases the activity of
oxidoreductases and increases the hydrolases
activity. In addition, the second content of humus
slightly increases and active acidity (pH) changes to
neutral. Accumulation of large amounts of iron oxide
(II) in soil is revealed
