Plant growth regulators are characterized by a wide range of biological effects: they activate plant life, increase productivity and improve product quality, strengthen protective properties of plants and increase their resistance to adverse growing conditions. The studies determined the influence of plant growth regulators “Zircon” and “Ribav-extra” on the physiological state of the cultivar ‘Ural 5’. The increase in the number of apple clonal rootstocks from 1 long meter when using the preparation Zircon with respect to the variant of “Ribav-extra” was 15.2 %. The average height of apple clonal rootstocks in the use of plant growth regulators ranged from 56.2 cm (“Ribav-extra”) to 65.3 cm (“Zircon”); after using the preparation “Zircon” the growth increased on 9.1 cm. The results of these studies have shown that the stimulating effect of the preparation is more manifested in the variant with “Zircon”. The plant growth regulator “Zircon” contributed to the formation of a larger number of apple clonal rootstocks from a long meter and increased the length of a clonal rootstock.
