Abstract

The formation of costs in the cultivation of fruit crops have their own characteristics. Before establishing perennial plantings, it is necessary to grow planting material. The high cost of planting material is due to the rather sophisticated technology of growing it. Nowadays, seedlings grafted on low rootstock and have 3 or more branches are chosen to lay modern intensive gardens, thus accelerating the formation of crown in the garden and the entry of trees into the the fruiting period for 1-2 years, as well as by its growth strength and reduction of harvest costs. For cultivation of sweet cherries planting material, summer budding and winter grafting are used, but in these methods seedlings are poorly branched or well branched, but with sharp angles of lateral branches offset. Spring grafting with long stalks can become a promising and resource-saving way of obtaining branched sweet cherry seedlings. This method does not require the use of a grafting complex, provides minimal costs for grafting care, there is also no need for special methods of seedlings branchings strengthening.

Highlights

There is a shortage of sweet cherry seedlings suitable for modern intensive gardens [8]
This method does not require the use of a grafting complex, provides minimal costs for care of rootstocks and graftings, there is no need to apply special methods and techniques for seedlings branching strengthening [2]
It should be noted that in the cultivation of branched sweet cherry seedlings using spring grafting with long stalks, seedlings with wide angles of side branches union were obtained, which simplifies further crown formation of trees in the garden

Summary

Introduction

There is a shortage of sweet cherry seedlings suitable for modern intensive gardens [8]. The main indicators of the quality of planting material are the well developed root system and the overground seedling part, which includes a certain number (3-6) of lateral branching with wide angles of branch union, which allows to accelerate the formation of crown in the garden and the entry to fruiting [5]. On their own, sweet cherry seedlings tend to branch poorly or do not branch at all. One of the main reasons for the lack of crown in plants is the weak biological ability of most varieties to branch
