Abstract

In order to evaluate the effects of BA on thinning, qualitative characteristics and antioxidant capacity in plum cv "Golden Drop", this research was conducted in Research Station of Agriculture, Tabriz University. A randomized complete block design (RCBD) with 5 treatments of BA (0, 50, 75, 100 and 125 mg / l) and 4 replications was arranged. Treatments were applied 14 days after full bloom on the selected branches. The thinning percentage and fruit quality parameters including total soluble solids (TSS), vitamin C, fruit diameter, length, volume, total flavonoids, total phenolic compounds and antioxidant capacity were measured. Results showed that BA significantly increased the amount of fruit thinning fruit, length, diameter, volume, soluble solids, vitamin C, titratable acidity and antioxidant capacity. Fruit firmness, total flavonoids and, total phenolic compounds were not affected by BA treatments. The highest fruit thinning belonged to 125 mg/L BA. In conclusion, BA caused significant thinning intensity and improved fruit quality of plum cv. "Golden Drop".
