title: Influence of concentration and formulation of macrosalts in the nutrient medium on the indicators of meristem regeneration at the stage of introduction to culture in vitro in some aboriginal Don grapes varieties
abstract: Abstract. Rare indigenous grape varieties are of significant value for viticulture, breeding and preservation of genetic material. Often, ancient grape varieties, due to prolonged vegetative propagation, are infected with one or more chronic diseases (viruses, phytoplasmas, bacterial cancer). The most reliable way to improve the health of such plants is the method of apical meristems in in vitro culture. In which, on artificial nutrient medium, it is necessary to regenerate the plant from isolat
