Abstract

In 2020-22, in a Pilot farm located 10 km east of the Guba regional center, the economic and biometric indicators of vegetative rootstocks of apple trees RV-4 (super-dwarf), 62-396 (dwarf), MM-106 (medium-sized), 54-118 (semi-dwarf), M9 (dwarf) and pears were studied. Ba 29 (medium-sized). PB-4 had the most intense monthly growth dynamics in August, while M9 and 62-396 had the most intense growth dynamics in August-September. In M 9, 4-5 cuttings with a height of 70-104 cm and a diameter of the root neck 8-10 mm were formed on the mother bush, MM 106 – up to 6 cuttings with a height of 63-82 sm and a diameter of the root neck 7-9 mm. In other rootstocks, the number of cuttings varied from 3 to 6, their height - from 63 to 111 cm, and the diameter of the root neck – from 6 (PB-4) to 10 mm (62-396). The results of this study help to better understand the similarities and differences in the biology and economically valuable traits of these rootstocks, which provides important clues for all players involved in the fruit growing sector.
