摘要：An experiment was conducted to study the effects of naphthaleneacetic acid at (10, 20 and 40 mg L^-1) and naphthaleneacetamide at (20, 40 and 80 mg L^-1), ethephon at (50, 100 and 200 mg L^-1) and urea at (0.2, 0.4 and 0.6%) 2 weeks After Full Bloom (AFB) in the commercial orchard in Neyriz, Fars Province in 2007 Iran. The factorial experiment was arranged in randomized complete block design with four replications. Some criteria were analyzed like percent of fruit thinning, fruit weight, volume, length and diameter, total soluble solids, total acidity, dry matter content and leaf area. The results showed that all chemicals except naphthaleneacetamide at 20 mg L^-1significantly increased percent of fruit thinning. All chemicals except ethephon had significant effect on fruit volume. The effect of naphthaleneacetic acid, naphthaleneacetamide at 40 and 80 mg L^-1and urea at 0.2 and 0.4% were significant on fruit weight. Total soluble solids were affected with chemicals and the highest level of total soluble solids obtained that by naphthaleneacetic acid at 40 mg L^-1. Total soluble solids/total acidity ratio significantly increased with naphthaleneacetic acid at 40 mg L^-1, all concentrations of naphthaleneacetamide, ethephon at 50 and 100 mg L^-1 and urea at 0.2%. The NAA at 40 mg L^-1, NAD at 40 and 80 mg L^-1, all concentrations of ethephon and urea at 0.4 and 0.6% significantly increased dry matter content of fruits and NAA, NAD and urea, increased leaf area.
