Effect of Different Concentrations of IBA and Time of Taking Cutting on Propagation of Black and White Myrtle (Myrtus communis L.) Cuttings

Abstract

This study aimed to evaluate the effect of different time of taking cutting and IBA concentrations on the rooting of Myrtus communis L. White and black myrtle types were used as plant materials. The cuttings were obtained from Batı Akdeniz Agricultural Research Institute (BATEM) collection garden. The effects of 0 (control), 500, 1000, 2000, 4000 and 8000 mg L-1 doses of IBA applications and time of taking cutting (February, March, April and May) on the rooting were investigated. The highest rooting percentage (76.67%) in black myrtle was obtained from cuttings taken in April and applied 1000 mg L-1 IBA, while the lowest rooting (10.00%) was obtained from cuttings applied 500 mg L-1 taken in May. White myrtle was rooted at a lower rate than black myrtle. It was determined that the highest rooting percentage (43.33%), shooting percentage (43.33%), rooted-shooted rates (43.33%) and average root number (1.63 pcs) in the white myrtle were 500 mg L-1 IBA dose in April. In addition, the study showed that the best rooting of white myrtle was in the cuttings taken in April and applied 500 mg L-1 IBA. Based on results, it can be concluded that time of taking cuttings in propagation and different concentration of IBA applications had a different impact on the success of black and white myrtle rooting.
