Abstract

The study of rootstocks group, providing the average vigor of growth for the grafted fruit plants, discovered their significant influence on the frost hardiness of the “graft-rootstock” system. The adaptivity of the plum varieties in the different graft and rootstock combinations was studied according to the “frost hardiness” criterion in the stages of the winter and spring development of the flower buds. The computer maps of the plum efficient allocation were created on the studied rootstocks, permitting to lay down the plantings with the lesser risks in the terms of climate fluctuation. It was established, that in the south of Russia the climatic conditions to cultivate Stanley variety on PK SK 1 rootstock, as compared with the rootstock of cherry plum seedling, mostly often used in industrial plantings of plum are mostly favorable. The conducted research contributes to isolation and allocation of the most adaptive graft and rootstock combinations based on their frost hardiness and, consequently, regularity of fruit-bearing and yielding capacity.

Highlights

To date, it is proved that a rootstock has impact on the vigor of plant growth, its resistance to the stress factors of biotic and abiotic nature [1,2,3]

It is proved that a rootstock has impact on the vigor of plant growth, its resistance to the stress factors of biotic and abiotic nature [1,2,3]. It is known very little about the manifestation of properties of the graft and rootstock combinations on the new rootstocks in the various conditions of environment and at the different stages of ontogenesis, this knowledge is necessary to expand the opportunities of regulating the vital functions of the fruit cultures and their varieties [4,5,6,7,8]

Summary

Introduction

It is proved that a rootstock has impact on the vigor of plant growth, its resistance to the stress factors of biotic and abiotic nature [1,2,3]. It is known very little about the manifestation of properties of the graft and rootstock combinations on the new rootstocks in the various conditions of environment and at the different stages of ontogenesis, this knowledge is necessary to expand the opportunities of regulating the vital functions of the fruit cultures and their varieties [4,5,6,7,8]. The rootstock is similar to the complex of the environment factors for grafting, and the interaction of grafting and rootstocks is similar to the mutual influence of the "genotype environment", for the mathematical description of which a lot of formulations has been developed by biometric genetics
