EFFECTS OF PLANT GROWTH REGULATORS ON QUANTITATIVE AND QUALITATIVE TRAITS OF 'SHAHANI' DATE (PHOENIX DACTYLIFERA) FRUITS
In order to evaluate the effects of plant growth regulators on quantity and quality traits of Shahani date fruits, this study was performed in two successive years as factorial in RCBD arrangement with 4 replications. Clusters of tested palms were pollinated with distinct and equal pollen and then treated with different concentrations of BA, GA3, NAA and 2,4-D, alone or in combination, in two stages: hababook and keimeri at ripening stage traits were measured including: ripening percentage, TSS, pH, water percentage, fruit and pit weight, length and diameter. Results showed that in treatments having 2,4-D the fruit size and in treatments having GA3 and BA the core size becomes large. TSS in the control treatment was more than other treatments. Treatments having auxin and GA3 showed delayed ripening in comparison with other treatments. Generally, treatments having BA with low concentrations of auxin and GA3 were suitable for improvement of quantity and quality traits of Shahani date fruits.
