| Abstract | ||||
| This trial was conducted during 2015 and 2016 seasons to found the best time of pollination of Saidy date palms grown under NewValley conditions. Pollination was done by spraying pollen grains suspension (5 g pollens/L water). Selecting the optimum period at which the female flowers of such date palm cv. remain receptive for pollination is very essential for date palm growers. Pollination was carried out on zero, two, four, six, eight and ten days from female cracking, besides the traditional pollination (seven strands / spathe). The date reveals that the time of pollination had an obvious impact on fruit retention%, yield and quality of Saidy date palms fruits. Traditional pollination with seven strands / spathe surpassed the pollination with improving grain suspension on product fruit retention %, yield and bunch weight. Fruit quality was greatly enhanced with pollination using pollen grain suspension over carrying out traditional pollination. Delaying times of pollination from zero to four days after spathe cracking caused a gradual promotion on fruit retention, yield and bunch weight. A gradual reduction on these parameters was observed with delaying times of pollination from 4-10 days after spathe cracking. Delaying times of pollination from 0-10 days after spathe cracking caused a progressive promotion on all physical and chemical characteristics of the fruits. Carrying out pollination with pollen grain suspension ( 5 g/ 1 L W) at two to four days after spathe cracking is considered the striking period of pistil receptivity and at the same time was necessary to produce appropriate yield and fair fruit quality of Saidy date palms grown under New Valley conditions, | ||||
