Estimation of environmental resources of fruit trees’ bearing in the South of Russia in the conditions of a climate change (exemplified by apricot in Krasnodar Territory)

Abstract

The work is devoted to the study of compromise between the adaptive properties of fruit crops and the conditions of their cultivation (exemplified by Red-cheeked apricot) at geographical points of Krasnodar Territory during a long period of years (1944-2018). The temperature criteria for a frost resistance of flower buds in winter-spring period were determined according to the phases of development. The research base has been created to study the requirements of apricot as to temperature conditions, has been predicted the regularity of its fruiting, depending upon the reappeared with climate change temperature stresses in winter-spring period. The assessment of a variety response to the new environmental conditions in time and space in tabular and graphical forms is given. The areas of Krasnodar Territory of varying degrees of favorableness for the stable apricot fruiting in the conditions of a climate change were elucidated.
