| Abstract | ||
| This experiment was conducted in the college of sciences university of karbala from 15/ 2 / 2004 till 15/ 6 / 2004 . The aim was to study the effect of : 1- The best cutting Length to be used . The concentration of the NAA which should be used in propagation.practices in order to obtain the highly possible rate of rooting.Experiment included planting cutting of three Lengths; VIZ ;( 15,20,25) cm , .After wounding and soaking cutting for 15 seconds in a solution of NAA at ( 500, 1000, 1500 ) ppm. the following characteristics were measured :percentage of rooting , roots number, roots Length, shoots number, leaves number, and the dry weight of leaves and roots. Acompletely randomized design ( C.R.D ) also adopted with 3replication . Means were compared using Duncan`s Multiple Range Test ( D. M. R. T ) at 5% probality level . | ||
