Резюме: The biotechnology of the process of micropropagation for cherry rootstock Maxma 14 is optimized. The experiments were carried out in 2017-2018, at the laboratory for in vitro propagation in Fruit Growing Institute – Plovdiv. Increased concentration of cytokinin BAPin multiplication period has an effect on plant proliferation. When BAP concentration is 1.0 mg.L-1, the multiplication coefficient is highest (6.87). A high rate of rooting is obtained in the nutrient medium B with 0,5 and 1.5 mg.L-1 IAA (93.33%). A lower percentage of rooting is obtained in the nutrient medium B, with IBA concentration 0.5 mg.L-1 (86.66%), but with better other indicators: root length, plant height and number of leaves. The best results in acclimatization are obtained in Float system.
