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

This study aimed to evaluate the effect of different time of taking cutting and IBA concentrations on the rooting of Myrtus communis. White and black fruity 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 in black fruity myrtle was obtained from cuttings taken in February and applied 1000 mg L-1 (76.67%) IBA, while the lowest rooting was obtained from cuttings applied 500 mg L-1 taken in May. White fruity myrtle was rooted at a lower rate than black fruity 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 fruity 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. As a result, it can be recommended to use the cuttings taken in April without any application for the best rooting in black fruity myrtle cuttings.
