Description
The immunologic characteristics of 18 domestic winter wheat cultivars to Transcaucasia population of yellow rust pathogen have been studied. 251 resistance sources to Puccinia striiformis have been detected among 468 studied soft wheat samples from Vavilov ARRIP collection. The efficiency of known resistance genes (Yr) to Transcaucasia population of yellow rust pathogen are estimated

Description
The plant body cells must contain a certain amount of water for a normal life. Water deficiency in cultivated plants was due to using herbicides used in intensive technologies of cultivation of agricultural crops. The conditions of the environment determine the sensitivity of the plant to herbicide. Soil and climatic conditions of winter wheat grown in the time of herbicide treatment are important for the effectiveness of its actions. It was found, that plants grown under shade or high humidity are more sensitive to herbicides than ones grown in bright sunlight and in times of drought. During drought, and in the open sunny spot, plant development is faster and become more stable. On soils rich in humus, we may grow less herbicide-resistant plants than in soils poor in organic matter. Herbicides are moved through the vascular system of plants with nutrients and metabolic products, they cause general poisoning as deformation of the stem and leaves of the plants, growth inhibition, chlorosis, fragility of leaves and stems, sterility, reducing the amount of free to bound water, which is particularly important for combating perennial weeds that have strong and well-developed root system. Monocots are able to immobilize the leaf herbicides. Latency of herbicides and their immobilization are carried out in various ways. Elucidation of the physiological characteristics that determine the resistance of plants to water scarcity and the effects of the herbicides is the most important task, the solution of which is not only of great theoretical, but also has practical significance

THE VARIABILITY OF TAXUS BACCATA CYPRESS CONES AT POPULATION OF DAGESTAN
DescriptionIn 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

Description
The article presents the results of the studies on the variability of morphological traits of the cenopopulations of Allium prostratum, Allium ramosum on the natural territory of the Yakutsk Botanical Garden and in cultura. We have performed researches of biometric parameters, which revealed the structural features of the plant and the nature of the variability of their parts. The article also gives an estimation of coenopopulations vitality

Description
The genotypic variability is submitted by a coefficient of variation, a genotypic diversification coverage - by a coefficient of heritability. Some attributes are recommended to the count in the Rapid Ecological Crop Trial (RECT). It is determined that pre-vegetation environment influenced on development of quantitative characters and the designed parameters.
