Abstract

This study was conducted during 2016 and 2017 seasons on about 10 years-old Barhee date palm trees grown in Agriculture Research Center farm at Toshka, Aswan Governorate, Egypt, as an attempt to solve pollination problems of Barhee date palm cultivar under heat stress. Seven pollination treatments were applied on flowers (T1) the normal (control) pollination by inserting ten male strands / female spathe, (T2) spray female spathes by sugar solution at 4g\L and then pollen grains were pushed out, (T3) pollen grains suspended in sugar solution at 4g\L and then spray on female spathes, (T4) spray female spathes by Borax solution at 4g\L and then pollen grains were pushed out, (T5) pollen grains suspended in Borax solution at 4g\L and then spray on female spathes. (T6) spray female spathes by NAA solution at 0.5g\L and then pollen grains were pushed out and (T7) pollen grains suspended in NAA solution at 0.5g\L and then spray on female spathes. Results revealed that spraying sugar, borax and NAA solution on female spathes of Barhee date palm before pollination or suspended with pollen grains significantly improved fruit set and retention besides, increased bunch weight, palm yield, fruit physical and chemical properties comparing with pollination by traditional method (control). The best treatment in this study was spraying female spathes by Borax solution at 4g\L and then pollen grains were pushed out. This study recommends spraying female spathes by Borax solution at 4g\L before pollination Barhee date palm trees under heat stress conditions.
