### Study of the Effectiveness of the Action of CAP and PTS on the Grafts  
CAP and PTS treatment of slant sections of plant shoots was carried out in March. When using a device for obtaining cold plasma, the duration of exposure to oblique sections of the cuttings was 15, 30 and 45 s, and when treated with a solution obtained by mixing PTS and distilled water (DW), with various concentrations of PTS (5%, 10%, 20%), the impact did not exceed 2 s. The air temperature in the greenhouse was maintained in the range of 30-35 \({}^{\circ}\)C. The degree of development of seedlings was assessed by growth (increase in length), the development of the deciduous part and the diameter of the root neck (Figures 8 and 9). Figure 8: The dynamics of the growth of cherry seedlings of the “Revna” variety within 4 months after planting in the greenhouse with direct treatment and different durations of exposure to CAP (15 s, 30 s and 45 s). Figure 9: The dynamics of growth of cherry seedlings of the “Revna” variety within 4 months after planting in the greenhouse with indirect processing using PTS diluted in DW in three proportions (1:5 (20%), 1:10 (10%) and 1:20 (5%)). As a result of monitoring the development of cherry seedlings of the \"Revna\" variety, we observed changes in the diameters of the root necks and the growth of the shoots within 4 months after vaccination and the effects of CAP and PTS on sections immediately before vaccination (Figures 10 and 11). The average diameter of the root collar during the processing of the scion cut with CAP for 15 s was higher than that of the control samples by almost 10%. With an exposure time of 30 s, the average diameter of the root necks was on average almost 20% larger. With an exposure time of 45 s, the average diameter of the root necks exceeded those of the control cuttings by an average of almost 25%. The most significant value for the growth of fresh shoots was obtained with the exposure of the inoculated components to CAP for 15 s, with the growth rate of the control samples exceeded by 17%; when exposed for 30 s, the growth of shoots was slightly lower than the control (\(-6.5\%\)); however, when monitoring the development of seedlings in the

Figure 10: The results of measuring the diameters of the root necks of cherry seedlings of the “Revna” variety within 4 months after planting in the greenhouse with direct treatment and different durations of exposure to CAP (15 s, 30 s and 45 s). fourth month of observation, the growth of the shoots relative to the control was about 9%; when exposed to 45 s, the increase was greater by 7% in comparison with the control. When wetting sections of grafts with PTS, similar results were obtained. When exposed to sections with a solution of 1:20 (5%), the average diameter of the root necks exceeded those of the control by almost 10%, and the growth rate of the shoots was 5% higher. When using a solution of 1:10 (10%), the average root collar diameter was increased by almost 5%, and the average growth rate was 10% higher than in the control group. When exposed to a solution with the highest concentration of activated liquid (1:5 (20%)), the difference in the average diameter of the root collars compared to the control was 20%, and the average increase was almost 30% more. Measurement of the electrical conductivity of the graft was used as a nondestructive method for assessing the qualitative intergrowth of graft components [27]. The measurement results are shown in Figure 12. The obtained results were compared with the control values. The lowest sensitivity value was found when exposed to CAP for 15 s; it was 23% lower than for the control. When exposed for 30 s, the result was 8.7% lower than the control, and when exposed for 45 s, the result was similar to that for the control.
