| Abstract | ||
| This study was carried out in the plastic house of collage of agriculture-university of Kirkuk during growth season 2015/2016, tow type of cutting was elected (woody, lush) from pear tree on old 5-6 years, the base of cutting immersed in four concentration of naphthalene acetic acid (0,500,1000,1500)mg.L-1for one minute. A factorial experiment with three replications was carried out using a randomized complete block design (R.C.B.D) with five seedling for each unit. The results showed that the wood cutting significantly increase on lush cutting in all the studded characteristics except rooted cutting ratio and seedling diameter. The 1000mg.L-1 treatment of NAA in all the studded characteristics. The be-interaction of studded factors showed that wood cutting and 1000mg.L-1 of NAA in shoot root dry weight, shoot fresh weight, seedling length, leaf number, chlorophyll, leaf area of seedlings significantly on other treatments . | ||
