【 摘 要 】

The aim of the research was to study the effect of the cuttings rooting period on the yield of high-quality rootstocks of stone fruit crops. In accordance with the developed methodology of research, modern rootstocks of stone fruit crops on the Crimean selection station Eureka 99 and Kuban 86 for plum, apricot, peach, and also VSL-2 for cherry and sweet cherry were studied. The paper presents the results of three-year experiments on the study effect of the rooting period hardwood cutting for standard stone seed root stocks. The data of mathematical processing the obtained results indicate the rooting period has a significant impact on the survival of hardwood cuttings. During the experiment, the average for the studied rootstocks during the autumn period of rooting, the survival rate of the cuttings was significantly higher than for the spring by 2.8%. According to the obtained data, on average, in terms of rooting for the stock Eureka 99, the highest survival rate of cuttings in experience was observed, significantly exceeding the figure of the other rootstocks by 21, 1-25, 4%. Output rates of standard rootstocks were adequate for the number of rooted cuttings. The results given in the article indicate that rootstocks Eureka 99 and VSL-2 have the highest yield of rootstocks per hectare observed during the spring planting season, exceeding the autumn planting dates by 109 and 217 thousand pieces respectively. The Kuban 86 rootstock has a reverse pattern. The article presents the results of sorting the obtained rootstocks by quality degrees. According to the data obtained, the highest yield of the first grade seedlings in the experiment was observed on almost all variants during the autumn term of rooting.
