Effect of pollination methods and pollen grains dilution on bunch weight and fruit quality of Sewy date palm, cultivar [electronic resource].

Includes reference.

The effect of pollen grain suspensions spray or pollen grains dust as a pollination method of Sewy date palm which combines with both mechanical pollination and fruit thinning was studied during- 2009, 2010 and 2011 seasons. Spraying method of pollination was conducted by using pollen grains at 0.4, 0.6, 0.8, and 1.Og/L mixed with O.2g boric acid and 10% sucrose as activating media. Pollen dust at 0.4, 0.6, 0.8, and 1.0g mixed with talc powder in ratio of 1:24 ,16,12,and 9 was also examined. The obtained results indi- cated that there were a reduction on the percentage of fruit reten- tion and bunch weight as the pol- len grains concentration was lower. There were no significant differences in bunch weight due to pollination with 1.0g pollen grains compared to control.
