Abstract
The article presents information on the testing of modified nutrient media used in the technology of micropropagation of strawberry varieties at the stages of multiplication and rhizogenesis in comparison with the traditional nutrient medium according to Murashiga and Skoog (MS). According to the results of studies conducted in the laboratory of agricultural biotechnology of the Stavropol State Agrarian University, the use of a modified nutrient medium at the stage of multiplication contributed to an increase in the multiplication coefficient of microcuttings relative to similar results of the control medium in the experiment by 0.4-2.5 units. Studies conducted at the stage of rhisigenesis showed a similar picture. In all considered strawberry varieties on the modified nutrient medium, more intensive root formation was noted, which led to a significant advantage of the results of the modified nutrient medium relative to the control on the 28th day of rhizogenesis by 15.0-18.7 %. Thus, it can be stated that the replacement of inorganic salts of microelements that are part of the nutrient medium with complexonates of microelements with a carboxyl-containing ligand - EDTA, contributed to a better development of experimental plants, an increase in the yield and quality of produced virus-free planting material of the studied industrial strawberry varieties.
