One year old branchs were pruned at levels of ( 25 and 50 %) at 15/ 1 / 2009 and sprayed with Zeatin at concentrations (100 and 150 ) mg/ L at 15 /3 /2009 alone or combination with pruning.

Results showed that pruning treatments and spraying with Zeatin treatments and their combination caused a significant increase in the leaf area ،leaf content of total chlorophyll ،IAA ، GA3 ،Zeatin ،percentage of carbohydrates and nitrogen in the branches.

Number ,length and diameter, of the branches as well as the duration of the vegetative buds open until the fall of leaves were increased, while the duration from fall of leaves until vegetative buds break was decreased, compared with control treatment.

There was a significant differences among treatments; treatment of pruning of branches at 50% and spraying Zeatin with 150 mg / L gave the highest values.
