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 describes the theoretical concept of environmental reclamation of nuts in the bio productive land reclamation of agricultural lands. Theoretical propositions formed the basis of technology of creation of bio productive plantings of walnut and black nut
In the present article, we have described data of comparative ampelography of biometric evaluation of leaf parameters of the three table grapes: Preobragenie, Victor and Jubiley Novocherkasska, widespread in the amateur and farming areas of Russia and the Ukraine
Features of a survival of self-sowing and undergrowth of oak (Quercus robur) under crones of a parent forest stand are considered
Ecological factors have a great impact on transition of a fescue meadow to formation of a bush. The optimum mode develops at high daily temperatures, in the rarefied crops, at security with nitrogen and without salinization
The article deals with the historical aspect of the formation of microbial-plant relationships. We study the details of the way the separate form components of the system "Microorganisms-plant" in the course of evolution. The research is based on the historical analysis of the interactions between microorganisms and plants. As a result of interactions a microbial-plant complex is formed. The article describes some types of interactions between microorganisms and plants. In general, various forms of symbiosis are components of a single evolutionary continuum
For the conservation of biodiversity, this study of
patterns of biological processes and phases in the
development of Convallaria majalis L. that are
repeated annually becomes actual. In the article, we
have presented an analysis of five years of
observations of the rhythm of the development of
Convallaria majalis L. in the conditions of the middle
Don. There were allocated phenological phases of lily
of the valley: vegetative (beginning of sprout growth,
deploying of leaves), bud formation, flowering
(disclosure of the first flower, mass blossoming, the
withering of separate flowers, the ending of
flowering), fruitage (the beginning of fruit setting,
mass of fruit setting, mass ripening of fruits), the end
of the vegetation (appearance of the first changes in
color of leaves, the complete drying). We have defined
daily average temperature and the appropriate amount
of positive temperatures for the passage of various
phases of development Convallaria majalis L. By the
results of two growing seasons, the optimal daily
average temperature for the flowering period is 14,3 °
C (the sum of average daily temperatures 161,3-204,
0С) - until 9-15 days. At higher daily air temperatures
flowering begins at lower amount of positive and
effective temperatures after 40-45 days after the start
of the vegetation. At lower daily air temperatures
flowering is longer than at higher. In the conditions of
the middle Don there were allocated some examples of
Convallaria majalis L. which bloom two years in a
row
In the article we gave the review of the results of treatment of bronchitis of young large horned livestock with electro-reflex therapy. The results of the treatment with the clinical process of the illness and the results of biochemistry of blood were also discussed
In the article we have determined the content of Co, Mn, B, Cu in typical soils and basic plant species characteristic of the main soil-vegetation belts the provinces foothills of Dagestan. It was found that the content of Co, Mn, B, Cu in soils and plants, and soil
fertility, respectively, increased in the system of natural landscape and vegetation belts of investigated province of Dagestan: steppe belt brown soil → dry steppe dark chestnut soils → forest belt of brown forest soils
Creation of complex compost provides the inclusion of about 10 kinds of organic and mineral wastes, the management of which optimizes their unification in order to create effective compounds, which noticeably change the physical, chemical and biological complexes by enhancing their long activity (4-6 years), ranging from their introduction into the upper layer of the soil, taking into account the development of microorganisms, strengthening water-physical links, enriching chemical ones and extending biological relationships with the expansion of ecological niches
