Date spines are usually removed from the new growth of fronds in the crown of the palm just before the pollination season to allow easy access to the date spathes as they emerge. If the palms have been dethorned the previous year, the new growth will be 2 or 3 rounds of fronds, each round developing 13 new leaves, a total of about 26 to 36 The pollination with cotton balls with a Gannami red had a significant variations in total sugar content percentage, reducing sugar and TSS. In comparison to normal (Natural) pollination with male Dijal method no significant differences found among most variations. Keywords: Date Palm, pollination, pollen sources, Total sugar. Introduction It was found that the date of the appearance of pollen on the palm affected by several factors, including weather conditions and especially temperatures. Early flowering occur in hot weather areas, as well as the variety of the pollinator. Floral inflorescence does not appear at the same time and may extend to 40 days (Shabana et al., 2002). ABSTRACT Date palms of the Fard cultivar were pollinated for three successive years using hand pollination (HP), hand duster (HD) and motorized duster (MD). One part of pollen was mixed with 5, 7 and 9 parts of wheat flour and applied by the hand and motorized dusters; whereas 3 inverted male strands per female spadix were applied by hand. Pollination of the date palm occurs naturally by the action of wind. However, for com‐ mercial production, it is necessary to artificially pollinate date palms [5]. Commonly, each farmer identifies the DPP source and extraction technique that gives the best results. It is Date palm pollen (DPP) plays a very important role in the fertilization process, since its viability and the pollination method influence on the quality, development, and yield of the fruit. In the present study, a broad review of its main characteristics, consumption, and DPP production are presented, as well as a description of its extraction methods and viability tests. The evolution of the In Siwi date palm Sarrwy et al . [32] found the the highest fruit set percentage with Rashid and Noubaria pollen grains. Fruit length Al -Hamoudi et al. [20] evaluated the some male types as pollinator for Barhi date palm cv. and studies the effect of these pollinators on fruit set and q uality of Barhi date palm. Date palm pollen (DPP) plays a very important role in the fertilization process, since its viability and the pollination method influence on the quality, development, and yield of the fruit. In the present study, a broad review of its main characteristics, consumption, and DPP production are presented, as well as a description of its extraction methods and viability tests. The evolution of the The date palm requires high temperatures and low humidity to set fruit and ripen to maturity. The date palm grows best in temperatures above 20°F (-7°C). However, they can survive into the mid to lower teens for short periods of time. For pollen germination, a temperature of 95°F (35°C) is needed. Financial establishment of a date palm plantation.
