Influence of climatic conditions of the Southern Coast of the Crimea on yield capacity of introduced peach cultivars Ambergold and Golden

Abstract

In Russian Federation peach is cultivated intensively in Southern regions, where it is the most important industrial stone fruit. In the Crimea it covers an area of 2.6 thousand ha, which amounts to 56.0% of the total area of stone fruit crops. Peach yield capacity depends not only on specific cultivar traits, but also on soil and climatic cultivation conditions. Global climate change caused decrease and deterioration in the state of fruit plants. The purpose of researches was to study the influence of climatic environmental factors on the formation of yield capacity of different peach cultivars. The research was conducted in 2015 - 2017 under the conditions of the Southern Coast of the Crimea by using collection plantings of the Nikita Botanical Gardens. Meteorological data during the periods of peach blossom, infestation with leaf curl and powdery mildew over a wide time span from 1990 to 2017, were collected and analyzed. To identify the features of the relationship of fruiting of each peach variety with environmental indicators, a correlation analysis was carried out. With the help of correlation analysis, the amount and substantiality of the connection of yield with climatic factors of the environment for each peach cultivar.
