Abstract
The article presents the results of evaluating the effectiveness of clonal micropropagation of the clone rootstock of cherry AI 70 (FSBSI NCFSCHVW breeding). In the course of the research, the influence of the chelated forms of iron Fe-EDTA and Fe-EDDHA, as well as the concentration of 6 BAP (0.75 and 1.0 mg/l) on the efficiency of shoot formation was evaluated. We took the Murashige-Skoog medium as the basis. The greatest number of shoots in the rootstock AI 70 is formed on MS medium containing Fe-EDDHA (100 mg/l) and 6 BAP 1 mg/l. At the first passage, the multiplication factor is 5.2 shoots/exp., at the fourth passage the number of shoots increases to 12.3 pieces/exp. On average, 8.8 new shoots are formed for each passage. In the control variant on MS medium with Fe-EDTA, an average of 6.6 shoots/exp.
