Abstract
Pollination of Sewy date palms with pollen grains carried by sucrose solution, talc powder, wheat flour, bran and starch in three different percentages namely 25, 50 or 75% of pollen grains were compared to ordinary pollination with 100% pollen grains only.
Results showed that using sucrose solution, talc powder, wheat flour, bran and starch as carriers for pollen grains was preferable than pollination with pollens only in improving yield and fruit quality. The promising effect was attributed to using sucrose solution, laic powder, wheat flour, bran, and starch, in descending order. Yield was positively affected by increasing percentages of the five carriers till 50% and at 75% there was a reduction on yield of palms.
From these results, the possibility of using 50% pollen grains in sucrose solution or talc powder as a carrier for Sewy date palm was arised. Such practice gave satisfactory promotion on the yIeld and gave the best results with regard to fruit quality rather than the conventional method of pollination with pollen grains only. These results were beneficial In early flowering season date varieties when the amount of pollen grains is not sufficient to accomplish pollination efficiency.
