Improvement of Winter Graft Techniques Using Cold Plasma and Plasma-Treated Solution on Cherry Cultures

Abstract

The description of a new method of winter grafting of sweet cherry varieties “Revna” is given. The novelty of the method lies in the use of a portable device for generating cold plasma, as well as a plasma-treated solution, developed by the team of authors. It has been established that exposure to cold plasma affects the growth length of “Revna” cherries by 17–28%, while an increase in the diameter of the root collar by 20–23% was observed. The electrical resistivity in the grafting zone after exposure to plasma or plasma-activated water decreased by an average of 14% compared to the control, which indicated a better fusion of the transport fibers of the rootstocks and scions.
