Abstract

Pollination is a critical process in date palm production lines that affects yield and fruit quality. The main aim of this study was to evaluate the effect of different pollination methods (dusting of pollination powder and spraying of pollen grain suspension with sugar or ascorbic acid) on yield and fruit quality of Barhy date palm. This study was conducted in El-Dakhala Oasis, New Valley during the 2019, 2020 and 2021 growing seasons. After three and six days of pollination, the modified approach (trimming 25% of tufts and setting 10 tufts/spathe plus dusting with 0.1 g pollen powder and bagging with shaking) or spraying female spathes with 1 g pollen grains + 10% ascorbic acid produced a higher performance yield and improved fruit quality. Furthermore, the proposed modified method of combining pollination and thinning has various advantages; including saving time, effort, labor and cost, and improving applicability, and can be recommended as a promising pollination strategy for the future.
