New method of propagation of clonal rootstocks of stone fruit crops

Abstract

One of the main measures aimed at developing highly productive plantations of stone fruit crops is breeding and selection of promising clonal rootstocks. A ground for the research served the need to develop effective technologies for propagation of clonal rootstocks. The article describes the method developed for the effective propagation of clonal rootstocks of stone fruit crops on the basis of the research conducted and the results obtained. The experiment was performed in a greenhouse complex with fog cannons in a scientific and production company. The aim of the research was to develop a method for effective propagation of clonal rootstocks of stone fruit crops, which would double the output of rooted soft wood cuttings. To achieve the goal, the period of rhizogenic activity was determined, an experimental research on the impact of auxin preparation IMK and 50% aqueous ethanol solution (control) on the size of stems, leaves and roots of soft wood cuttings was performed. The research helped to develop a new method for effective propagation of clonal rootstocks of stone fruit crops. The methods extended the timing of cutting in favor of early forms due to the use of soft wood cuttings, auxin stimulator of rhizogenesis, substrate in container cassettes, which in turn more than doubles the efficiency of expensive greenhouse area.
