| Abstract | The generalized analysis of productivity of uterine plantings of a clonal rootstock of pumiselect gives the basis to consider that the positive result can be received at reproduction of rootstocks both in vertical, and horizontal ways. The vertical method of uterine plantings allows to obtain clonal rootstocks annually in the amount of 38.67-42.00 thousand units / ha, including rootstocks, which according to their biometric indicators belong to the 1st commodity grade – 22.67-28, 67 thousand pieces / hectare, or 49,28-52,44%. The share of rootstocks that did not meet the requirements of DSTU 4791: 2014 was 19.33%. The horizontal method of uterine plantations allows to obtain clonal rootstocks in a year in the amount of 98.99 thousand pieces / ha, including rootstocks, which according to their biometric indicators belong to the 1st commodity grade - 54.33 thousand pieces/ha, or 43.35%. The share of rootstocks that did not meet the requirements of DSTU 4791: 2014 was 21.01%. It should be noted that a significant number of rootstocks had biometric indicators of medium development (2nd commodity grade), which is a reserve that can significantly increase the productivity of uterine plantations. Thus, the yield of the highest quality number of rootstocks (1st commodity grade) is approximately the same and does not depend on the method of planting. At the same time, the total yield of standard rootstocks in the management of uterine plantations of the two-year cycle (horizontal method) is 98.99 thousand units / ha and exceeds the productivity of plantations for two years of the one-year cultivation cycle (vertical method) by 22.71%. | ||
