Impact of different times and methods of pollination on fruit set and productivity of barhi date palm [electronic resource]

Includes bibliographic reference

This study investigated the effect of different pollination methods, traditional
pollination (hand pollination), spraying pollen suspension and dusting pollen
and different pollination times (at same spathe cracking day and after two
days from spathe cracking) on fruit set (%), yield as well as some fruit physical
and chemical properties of “Barhi” date palm cultivar. The used palms grown in
new reclaimed sandy soil at private orchard located at Al Assiuty valley, Assiut,
Egypt during two consecutive seasons (2020 and 2021). Results cleared that the
most effective treatments in this investigation is using hand pollination at same
spathe cracking day followed by spraying pollen suspension at same spathe
cracking day, these treatments gave the highest fruit set% with economical yield
and high fruit quality with high content of total and reducing sugars. However,
delaying the pollination two days after spathe cracking resulted in decreasing
fruit set, yield and fruit quality compared with pollination at the same spathe
cracking day.
