Abstract

Experiment were conducted to investigate the effects of foliar application of gibberellic acid on fruit chemical characters in ‘Barhee’ date palm carried out during the 2023 and 2024 seasons in at El-Mansoria district (Egypt - Alexandria Desert Road), El-Giza Governorate, Egypt. GA3 (5, 10, 15, 20, 25 ppm) was applied to the Date palms during both seasons. Fruit under control were sprayed with tap water only. Investigate were recorded on fruit chemical characters like TSS (%), Titratable acidity (%), TSS/acid ratio, Total sugars, Reducing sugars, Non-reducing sugars, Tannins (%), Phenols (mg g-1 Fw), Total chlorophyll (mg/100 g Fw), Total Carotenoids (mg/100g Fw) and Rutab (%). Results indicated that GA3 concentrations spray either during 2023 and 2024 seasons. Favorably influenced all fruit chemical characters of ‘Barhee’ date palm over control. In all, to investigate the effects of foliar application spraying GA3 during both seasons was very much more effective in achieving the desirable results.
