The results of studies on the development of culture medium for initiation grape meristems into in vitro culture in order to increase BREAST/NIPPLE their regenerative capacity during recovery from chronic diseases are presented.In the improved medium, in comparison with analogs, the total content of macro salts was reduced and their ratio was optimized, taking into account their consumption and the characteristics of their absorption from the nutrient solution by the grape plant.In the course of testing the new culture medium, its effectiveness has been established for grape varieties from various ecological and geographical groups.
A higher and more stable percentage of survival and regeneration of extremely Pre-Natals small meristems have been established against the background of various modifications of the recipe for the traditionally used culture medium of Murashige and Skoog.
