Apricot productivity in the northern part of the country under the influence of abiotic factors

Abstract

The object of the research was the trees of the apricot varieties of Spring Blush, Pinkcot, Kyoto and Faralia, grafted on the Mirobalan 29C rootstock. Planting distance was 4.0x2.2 m. The planting of apricot trees was carried out in spring of 2018. Trees were trained to a Trident canopy. During the research was studied the morphological parameters of fruits and seeds, shape index, productivity and fruit redistribution quality classes. It was established that the biological characteristics of the variety influence the plantation productivity and the redistribution of the fruits in different quality classes. The Kyoto variety had a higher resistance to the late return temperatures, which in the conditions of the northern area registered productions of 17.03 t/ha in the third year after planting.
