METHODS OF ASSESSMENT OF BIOMORPHOLOGICAL CHARACTERISTICS AND BIOCHEMICAL PROPERTIES CHARACTERIZED ADAPTABILITY OF ZIZYPHUS JUJUBА MILL. FOR MULTIFUNCTIONAL PLANTINGS
Geographical variation, adaptability and reproductive ability of plants associated with the expression of ecological plasticity in conditions of introduction, are means of establishing the biological parameters of each species to the relevant environmental conditions of the environment. The material is designed to address methodological issues of introduction, maintenance, enhancement and continuous use of the biodiversity of woody species for the development of sustainable multifunctional agroforestry systems. Tthe problem of adaptation and selection of plants based on the study of the biological parameters of the species as a whole and comprehensively taking into account the amplitude ecological and physiological variability of plants, their ability to seed reproduction becomes more relevant. The authors developed a method for estimating of biomorphological characteristics and biochemical properties that characterize the adaptability of Zizyphus jujubа Mill. (jujube) for multifunctional plantings. It is based on an assessment of the biological potential of plants in the system of "genotype-environment", as well as reproductive features of the selected target using its own biological resources with the possibility of a comprehensive study and evaluation of the economic suitability of varietal diversity. The authrors developed the methods of identification of patterns of growth and development of bushes depending on the limiting factors of the environment, the determination of the adaptation possibilities of jujube cultivars in the conditions of light-chestnut soils, evaluation of biochemical composition of fruits (total sugar, rutin, ascorbic acid), depending on the ripening and varietal facilities.
