Impact of Pollen Source on Yield and Fruit Quality of Hayany Date Palm (Phoenix dactylifera L.)

Document Type : Original Article

Abstract

 THE INFLUENCE of pollens introduced from three different locations., Aswan, New Valley and Balteem on yield and fruit quality of Hayany dates were estimated in the experiment conducted in a private orchard, Egypt during 2009 and 2010 seasons. Nine Hayany female trees grown in Beheira governorate and three male palm trees (M1, M2 and M3) were selected, one from each location, respectively. Results indicated that pollen source significantly affected the final fruit retention percentage as minimum fruit drop was observed from trees pollinated with M1 (Grown in Aswan). Fruit weight, flesh weight and fruit volume were significantly improved with pollens from M1 palm trees compared to other male trees. Soluble solids, ascorbic acid, anthocyanin and total and reducing sugars were the highest in fruit pollinated with M1 and M2, respectively. Whereas the highest level of tannin and crowed fibers were recorded in fruits pollinated with M3. In conclusion, the pollen source had significant impact on the physicochemical properties of date palm cv. ‘Hayany’. Results suggested that the best pollen source (Male trees) should be selected for female trees to get the most desired characteristics.
