The purpose of work - to solve several questions of methodology of assessment and to develop system of an estimation of the basic agricultural crops of southern region to abiotic stress on the basis of studying of physiological mechanisms of formation and realization of adaptibility and to create valuable source material for practical breeding. Methods of research - physiological, biochemical and agrobiological methods in natural conditions and conditions of an artificial climate with usage of biological statistics. The analysis of the most important agricultural parameters of weather conditions of the autumn-winter period of southern region for the last 30 years has shown reduction of duration of the temperature conditions favorable for hardening of plants of winter crops; increasing in fluctuations of dynamics of duration of a favorable temperature mode for passage of the first phase of hardening of winter wheat plants; increasing in an index of continentality of climate; growth of a temperature background in autumn period; deterioration of conditions of moisture content due to increasing of ineffective and inefficient for an agriculture rains and downpours. The system of an estimation of agricultural cultures on resistance to negative influence of temperature stress is worked up on the basis of developed, modified and optimized for needs of practical breedig ways of an estimation considering the estimated tendencies of changes of weather conditions of southern region. The evaluation is given to 2450 samples of five agricultural crops on four parameters of adaptibility. For scientific maintenance of agricultural sector, on the basis of the developed technique of an evaluation of formation of winter hardiness, constant monitoring of the condition of an overwintering of winter crops on fields of the institute and farms of the Odessa region was carried out. Realization of results is recommended to be carried out by using of the methods and recommendations for carrying out of modelling researches and an evaluation of breeding material on adaptаbility of the basic agricultural crops to temperature stress for an obligatory evaluation of genotypes on thermoresistivity in Breeding and genetics institute and the domestic scientific profile establishments engaged in breeding and seed growing, in Public service after protections of the rights to grades of plants, in the hydrometeorological centres, and in the farms as well Product Description popup.authors Феоктістов Павло Олександрович popup.nrat_date 2020-04-02 Close
