Peculiarities of apple fruiting on the lower terrace of the Krutovsky Botanical Garden

Abstract

The paper provides an assessment of the frequency of apple fruiting of different maturation periods growing on the lower terrace of the Vs. M. Krutovsky Botanical garden in the period from 2015 to 2018 according to the following parameters: the number of fruit-bearing trees, the number of fruits on the tree, yield. In the conditions of the Botanical garden, located in the green zone of Krasnoyarsk, the timing of the onset of removable fruit maturity varies significantly. The variability of the fruit formation period depends on the weather conditions in the summer and primarily on the temperature regime. The optimal time for collecting varieties of the summer ripening period is August, and for winter varieties is September, since by this time the fruits of these groups acquire a characteristic color and size. It was found that during the research period, most of the trees of the presented varieties fruited annually. Varieties and individual specimens with an annual plentiful fruiting and maximum fruit weight of fruits are selected: Bismark, Belyy Naliv, General Orlov, Grushovka moskovskaya, Zolotoy Ship, Papirovka, which is a positive factor in a sharply continental climate. It was found that in Siberia, varieties adapted to the European zone have successfully adapted and can be grown in these and similar climatic conditions and can be recommended for further breeding.
