Abstract

A factorial with two factors and three replication experiment was conducted in the horticultural and forestry station- Mahawell-Babil.Goverment during Sep.2007 to Nov.2008 to find out the effect of bud treatments with benzyl adenine at concentration (0, 100, 200 and 300 mgL) and foliar spraying with Grow More nutrient solution at different intervals (no spraying ,15 and 30 days interval) on some growth characters of pear grafted on Callyriana rootstock . Results indicated that BA atconc . of 300 mgL results in the highest percentage of budding success and higher values of stem height, shoot number, shoot length, leaf area and dry weight as compared to the control treatment . On the other hand , foliar spraying with the nutrient solution at shorter interval ( 15 days ) gave the highest means of the above mentioned vegetative Parameters . The interaction of the mentioned interval of foliar spray and the growth regulator at conc . of 300 mg/l also gave the highest values of the vegetative studied Parameters .
