Abstract

This study was conducted to evaluate soft as well as hardwood cutting and trench layering for propagation of F12/1 rootstock. The effect of IBA on rooting of soft and hardwood cutting in this rootstock also studied. The IBA treatments were 0, 1000, 2000 and 3000 mg/l. the experimental design was a randomized complete block one with four replications. Evaluation was on the basis of the rooting percentage, number and length of first and second grade roots as well as length of rooted portion of cutting. In softwood cuttings the rooting percentages were 75%, 65%, 60% and 55% in 1000, 0 (control), 2000 and 3000 mg/l, respectively. Number of first and second grade roots, length of rooted portion and callus formation increased with increase in concentration of IBA but the lengths decreased, although there was no significant difference observed among some IBA concentrations. As for hardwood cuttings callusing occurred but cuttings rotted and didn’t from roots. In layering operations on overall 73.3% of shoots on layered stems were rooted.
