Gogulinckaya Y. Development and improvement of methods in assessment of stress-factors resistance for grapevine by using of in vitro culture

Оbject - processes of growth and development of grapevine microclones. Aim - development and improvement of rapid methods in assessment of drought and salinity resistance for grapevine by using of in vitro culture. Methods - biometrical, physiological, biochemical, biophysical, biotechnological, statistical. Novelty - the influence of stress agents (polyethyleneglycol, various types of salts) consisting of growth media on the growth processes, physiological, biochemical and biophysical parameters of grapevine mikroclones in vitro conditions have been determined, for the diagnostic of drought and salinity resistance of grapevine mikroclones have been proposed the coefficient and the scale to assess stability, the method of induction of chlorophyll fluorescence of leaves has been used. Results - rapid diagnostic methods in assessment of drought and salinity resistance for grapevine in vitro conditions have been developed, the use of the improved methods promoted savings of 21% and reduced the selection process on average of 6 years. Branch - viticulture.
