The article highlights the research results on the rooting of green pear and quince cuttings in the first and second decades of June. Green cuttings were taken from mother shrubs and treated with the plant growth stimulator of succinic acid. As the pear and quince cuttings took roots, we determined the rooting ability of rootstocks, number of standard rootstocks, height of the rooted rootstocks, diameter of the conditional root neck, number of roots, length of the root system. The rootstocks of pear PG 12 (k), PG 2, PG 17-16, PG 333 and quince VA 29, Severnaya demonstrated the best indicators of rooting ability, number of standard rootstocks, diameter of the conditional root neck, number and length of roots.
