Abstract: 
An experiment was conducted in order to determine the effect of Paclobutrazol (PBZ) on several vegetative and reproductive trails, such as Relative water content (RWC) trunk cross sectional area (TCSA), fruit set and flower bud initiation. Four treatments were alTanged in randomized complete block design with five replications. Treatments were: T1=0, T2=0.25, T3=0.75, T4=1.25 grams soil application s paclobutrazol per tree.
Results showed that: PBZ had no effecr-on RWC but reduced CUlTentseason growth and TCSA. In 2003 (second year after treatment) treatment 3 and 4 were delayed blooming time for 2& 3 days respectively. Despite of flower bud formation were not modify by treatments, initial fruit set and final fruit set were increased by PBZ. Although no changes were observed in leaf P & K content but N content were increased by PBZ treatments.
