DIFFERENT APPROACHES TO IN VITRO ROOTING POSSIBILITIES IN PRUNUS ROOTSTOCKS

Abstract

The possibility of vegetative propagation is one of the most essential criteria in the breeding rootstocks. In this mode of propagation, in vitro propagation has taken the place of propagation by cuttings with the development of technology. In vitro propagation practices are used effectively by nursery enterprises. Firms try different modifications and application forms to achieve maximum success in this form of propagation. In this way, it is tried to create optimum propagation protocols. This study aimed to increase the rooting possibilities of clone rootstocks by applying different IBA dip applications. The study was carried out in the laboratories and greenhouses of the Eastern Mediterranean Transition Zone Agricultural Research Institute in 2022. At the end of the study, it was determined that the average root number per explant varies between 0-2.36 explants, and the average root length varies between 0-9.40 cm in the applied clone rootstocks. When the study results were compared with similar studies, it was determined that the results were promising. According to the results obtained from the study, it was thought that immersion in an IBA solution before rooting could be a solution for some clone rootstocks with rooting problems.
