Abstract:
The scientific article presents the results of study on the influence of vegetatively propagated
low-growing rootstocks and types of artificial forms of crown cherry and sweet cherry on the
development of the leaf apparatus of such varieties of cherry Shubinka, Podbelskaya and
Shpanka Chernaya (black), sweet cherry Bahor, Revershon and Drogan Zheltaya (yellow).
Research has shown that the formation of leaves and the development of the assimilation
apparatus of both a single tree and a unit of garden area significantly depends on the genetic
characteristics of the variety, the selected rootstock when growing planting material, as well as
the method of crown formation. Maximum conditions for the development of the assimilation
surface of the cherry variety Shpanka Chernaya (black) are provided on the VVA-1 rootstock
when forming a crown of the fruit wall type with five-skeletal branches left in the aboveground
part – 39.01 thousand m2/ha. In the sweet cherry variety Revershon, the largest assimilation
surface – 57.90 thousand m2/ha was observed on the rootstock VSL-2 (Krymskaya-5) when
using the KGB crown shape (Kim Green Bush). As a result of the conducted research, it was
found that the optimal crown system for cherry and sweet cherry varieties is the five-skeletal
wall. In this case, the leaf activity index of plants reaches 3.7-4.4 m2 per crown projection area |
