A STUDY ON CLONAL PROPAGATİON BY CUTTING OF NATIVE BOXWOOD SPECİES B. balearica
Ömer SARI
Abstract
The aim of the study was to determine the reproductive parameters of the endangered B. balearica species, which is naturally distributed in Turkey, under in vivo conditions. The effect of 0, 2000, 4000 and 8000 ppm doses of IAA and IBA on the rooting of semi-wood cuttings of B. balearica was investigated. As a result, it was the 4000 ppm application that increased the root length (5.4 cm) and root width (5.6 cm) the most compared to the control. Her iki hormon uygulamasında da 8000 ppm was the most effective application on root number (6 per plant) and root quality (3.1 and 3.0). In addition, the most effective application on shoot length (1.8 cm) and the number of leaves on the shoot (7.5 per shoot) was found to be 8000 ppm. Regarding the callus rate, 4000 ppm (21%) was the most effective application in both hormone applications. In terms of rooting rate, 8000 ppm IBA provided a 98.5% higher rooting rate compared to the control. Although hormone applications had different effects on root morphologies, IBA showed a better performance than IAA on rooting rate. Additionally, phytohormone applications had a positive effect on rooting.The data obtained can be used to propagate existing boxwoods in landscape areas and for the rehabilitation of disappearing forests.
