Effect of Different Concentration of BA on Thining Intensity, Fruit Qualitative and Antioxidative Characteristics of Prunus Domestica Var. Golestan

One of the major problems in fruit production is the reduction of yield and quality. Benzyl adenine plays an important role in regulating the growth of plants. Therefore, this study was designed to examine the effect of different concentrations of benzyl adenine on thinning rate and the qualitative and antioxidant characteristics of fruit in greengage.

Materials and Methods: The experiment was conducted as a randomized complete block design with 5 benzyl adenine treatments (60, 90, 120 and 150 mg/L) in 4 replications. The solution were applied two weeks after the full bloom on the selected trees. Then, the thinning percentage and fruit quality parameters such as total soluble solids (TSS), acidity, vitamin C, diameter, length, volume, weight, firmness, flavonoids, phenols, and total antioxidant capacity of the fruit were evaluated at the commercial harvest.

Results: The results showed that the application of benzyl adenine had different effects on the quality and antioxidant properties of greengage fruits. In all traits excepton flavonoids and total phenols, the effects of treatment were significant at the level. The highest percentage of fruit drop and antioxidant capacity were observed at a concentration of 150 mg/L.

Conclusion: In general, benzyl adenine has a significant effect on thinning and improving the quality and antioxidant characteristics of Golestan cultivar fruits. The use of a 150 mg/L concentration of benzyl adenine provided the best results in antioxidant capacity and fruit quality improving. This study could offer a new approach for enhancing greengage production and increasing its quality in agriculture.
