Abstract: 

This experiment was conducted to investigate the effects of plant growth regulators on the quantitative and quality traits of Shahani date fruits, in two consequent years as factorial experiment in RCBD arrangement with 4 replications. Clusters of palms were pollinated with distinct and equal pollen, and then were treated with different concentrations of Benzyl Adenine (BA), Gibberellic acid (GA3), Naphthaleneacetic acid (NAA) and 2, 4-Dichlorophenoxiacetic acid (2,4-D) alone or in combination together, at two stages: Hababook and Keimeri. At the ripening stage traits including: ripening percentage, TSS, pH, water content, fruit and seed weight, length and diameter were measured. The results showed that fruit sized increased in treatments had 2,4-D and seed size increased in GA3 and BA. TSS in control treatment was more than other treatments. Treatments having auxin and GA3 had a delayed ripening than other treatments. Generally, treatments having BA with low concentrations of auxin and GA3 were suitable for improvement of quantitative and qualitative traits of Shahani date fruits.
