Abstract
A field experiment was conducted in the College of Agriculture / University of Karbala by using polyethylene bags in diameter (22cm) containing loamy soil and peatmoss mixture by volume of 3 : 1 during the period between the beginning of December of 2013 until the end of the November 2014 . A factorial experiment carried out by using a Randomized Complete Block Design (R.C.B.D.) with three blocks each experimental unit contained (10) cutting data were analyzed statistically and compared to the averages of the Duncan's Multiple Range Test at 5% to study the effect of three types of stem cutting (basal , intermediate and terminal cutting) , length (25cm) and diameter (6-8 mm) had been taken on three dates (4/12/2013 , 4/1/2014 and 4/2/2014) and treated with three concentrations of Naphthalene Acetic Acid (500 , 1000 and 1500 mg.liter-1) as well as the treatment control treatment , all cutting were rapid immersion for a period (15 seconds) on some vegetative growth of the mind of willow trees (Salix babylonica L.) . The results indicated that there was a significant differences between treatments in all studied parameters . Terminal cutting was superior in all parameters as compared with both intermediate and basal cutting , as well as the third date of collection significantly improve cutting parameters as compared with both second and third dates , also the cutting treated with third concentration of Naphthalene Acetic Acid concentration (1500 mg.liter-1) was superior in all parameters compared with control treatment .
