Study of the adaptability of scion-rootstock combinations of plum tree to temperature stressors in the Krasnodar Territory

The relevance of the research is due to a change in strength, frequency and direction harmful weather stresses associated with climate change, which has an extremely negative effect on general condition productivity plants, disrupts conditions for exit plants from dormant stage, while accelerating rate spring development. rise positive temperatures autumn period delays entry into phase organic dormancy, impairing their preparation winter. This paper provides assessment adaptive response optimal course growth development scion-rootstock combinations (SRC), taking account changes environmental conditions. complexity interaction mechanisms “scion-rootstock-environment” system presented. Analysis variance shown that quantitative traits have complex genetic systems, are characterized by multivariance reaction multilevel redefinition organization SRC when changing limits. value work fact selected objects perennial fruit crops, interacting two genotypes. best grafts rootstocks studied varieties specific given growing technologies were identified: Stanley / PK SK 1, Druzhba, Renklod Donetskiy-1 Evrika 99, cherry plum, Milena 99 highest-yielding under changed conditions, hence most adaptive, plum variety 1 Druzhba.
