Abstract

This study was carried out to investigate the effect of wounding by different methods, wounding : base of cuttings, split cut at base of cutting and longitudinal cut at the base of cuttuings on rooting of MM 106 cuttings. Cuttings were also treated by 0, 1000, 2000 and 3000 ppm IBA concentration. This effect was more obvious due to wounding + 2000 ppm IBA at the first season. Highest percent of rooting was recorded (86.66 %), number of roots (4.00) and total root growth of roots (16 .80 cm). In the second season, split cut at base of cuttings + 2000 ppm IBA caused an increase in rooting percent (86.66 %),
