Bushylov V. The improvement of the cultivation technology of clone rootstock Pumiselect and peach seedlings

The object of research is the technological components of the production of clonal rootstocks by cuttings, woody cuttings and peach seedlings. The purpose of the study is to improve the main technological components of propagation of clonal rootstock Pumiselect and peach seedlings. Research methods - field, laboratory, laboratory-field, mathematical-statistical, calculation-analytical.For the first time, a comparative study of the methods of growing Pumiselect clonal rootstock by cuttings (vertical and horizontal) and woody cuttings. The productivity of uterine plantations on cultivation by vertical and horizontal cuttings is established. The basic elements of Pumiselect clonal rootstock production by the method of grafting, the dynamics of the parameters of mother plants depending on their age are highlighted. Phytometric indicators and productivity of the uterine-cutting garden, qualitative and quantitative characteristics of shoots are revealed. The influence of cuttings terms, localization of cuttings on rooting and quality of the received cuttings is proved.It is argued that the cuttings are better rooted, which are harvested from the basal part of the most developed shoots and mulching the soil with a black polymer film. It is shown that there is a stable correlation between the biometric parameters of the leaf blade and its area. The compatibility of Pumiselect rootstock with peach varieties has been established. It is substantiated that the cultivation of Pumiselect rootstock by horizontal cuttings, grafting of woody cuttings and peach cultivation on Pumiselect rootstock is profitable and profitable.
