Sideleva I. The method of rapid assessment of sugar beet tolerant forms for water deficit using in vitro culture.

This thesis presents the results of research to develop methods of rapid assessment of sugar beet tolerant plants for water deficit using in vitro culture. It was carried out a comparative evaluation of hybrids of sugar beet by the number of stomata cells and chloroplasts. Cultivation media for identification of genotypes with higher adaptive capacity were made. The distribution of the studied hybrids for their tolerance to osmotic stress conditions using biochemical indicators of the antioxidant system status between sugar beet plants and analysis of their dynamics in osmotic stress conditions was carried out. Specific features of correlation connections between the conditions for plant cultivation and biochemical indicators of physiological status, which are important for the identification of adaptive mechanisms for sugar beet plants under water deficit conditions. The theoretical conclusion and a new solution of an important scientific problem in development and experimental verification of the method of rapid assessment of sugar beet tolerant plants for water deficit using in vitro culture.
