Description
Estimation of blast resistance of rice breeding lines, carrying resistance genes Pi-b, Pi-z and Pi-40 has been done. For phytopatological test isolates of pathogen from Krasnodar territory were used. As the results of the study Pi-40 gene showed maximal resistance to blast isolates. On the other part, rice line, carrying both genes – Pib and Pi-z showed significantly higher level of resistance with compare to standart variety Khazar

EVALUATION OF THE QUALITY OF WHEAT MALT GROWN USING ELECTRO-ACTIVATED WATER SOLUTIONS
DescriptionThe present review highlights possibility of obtaining wheat malt by using electro-activated water solutions obtained by electrolysis

Description
As result of evaluation 24 common wheat introgression lines with genetic material Agropyron glaucum the considerable variability of resistance to leaf rust was revealed. Genetic control of leaf rust in introgression lines 60 and 109 was studied using hybridological analysis. Both lines contained single dominant genes differed from each other and from the known effective Lr19 and Lr24. The investigated lines with genetic material Agropyron glaucum are valuable donors of the genes for leaf rust resistance

ESTIMATION OF ACTINIDIA DELICIOSA CULTIVARS (KIWI) ADAPTIVE POTENTIAL IN RUSSIAN SUBTROPICS
DescriptionThe influence of climate factors on adaptiveness of Actinidia deliciosa strange cultivars is ascertained in damp subtropics of Russia. The basic limiting factor of its cultivation is precipitation quantity during flowering phase and fetal maturity

SELECTION OF PERSPECTIVE BIOLOGICAL CONTROL AGENTS FOR FALL WHEAT PROTECTION FROM FUSARIUM DISEASES
DescriptionThe results of primary screening of bacterial strains on the basis of cell-wall degrading enzymes and antifungal activity against the fungus Fusarium graminearum. Selected active strains perspective for the development of biopreparations based on their type of multifunctional action to protect fall wheat from Fusarium pathogens are given

FEATURES OF THE EVOLUTIONARY DEVEL-OPMENT OF LIFE FORMS OF HIGHER PLANTS
DescriptionClimatic cycles associated with global phases of create gasses are the reasons of oscillation ecosystems and their constituent. Ecological capacitance of systems increases or decreases due to the appearance of new ecological niches, which creating favorable conditions for expanding or narrowing opportunities of adapting new types of organization of living organisms and their significant changes. Conjugacy of the biological evolution of living organisms with geological crises and periodic variations in solar activity is observed. Direction in the development of plant life forms since the beginning of their occurrence was quite varied. The most deeply the development of life forms was developed for flowering plants, starting from of different groups of gymnosperms. The main reasons for selection of life forms are due to challenges facing researchers

Description
The article presents data on the growth of an assimilation apparatus of Scots pine, silver birch and pedunculate oak in the conditions of the Lipetsk industrial center. It is established that the growth dynamics of annual and biennial needles of Scots pine under pollution is higher compared to the control, while absolute values of length and mass of needles less. Starting from the second year, in the conditions of contamination noted stunted pine needle growth, which increases by the third year. It is shown that the linear dimensions of the lamina of birch in the conditions of pollution are not changing much compared to the control, whereas the linear dimensions of the lamina of pedunculate oak in the conditions of pollution is less than the control

Description
The soil properties out of playing areas of golf courses (so-called roughs) have an influence on the lawn vegetation state. Heavy texture of the soil has the cause of deterioration of the water-air properties of soil which is accompanied by changes in the nature of addition grass lawn from solid to mosaic. Non-aggressive grass of the artificial lawn has one of the reasons for renewal of native flora and the formation of a new type of plant association, closer to the natural vegetation of the Don floodplain

Description
The analysis of change of oak participation as a part of planting depending on directions of a slope, forest stand height along a slope (top, average, bottom) and cutslope ratio (5 – 15º and 25 – 35º) on time length bor 25 years is carried out. Oak durmast and english oak serai changes directions are revealed on the Western Caucasus
