| Abstract | ||
| This investigation was carried out during two successive seasons (2006 and 2007) in Balteem district, Kafr El-Sheikh governorate, Egypt, aiming to investigate the influence of different pollination levels on fruit quality of “Hayany” date palm compared to the level pollination used by farmers (9 strands / inflorescence). Five healthy female date palms were selected, 12 spathes (inflorescence) were left on each one. Four levels of pollination were applied; 3,6 and 12 strands/inflorescence and control (9 strands / inflorescence, farmers level pollination). The results showed that fruit set percentage increased by increasing pollination level in both experimental seasons. Bunch weight increased in treatments 3 strands/inflorescence and 6 strands/inflorescence and declined by increasing pollination level to record the lowest values by treatment 12 strands/inflorescence and control. The highest acidity and tannins content were recorded by 12 strands/inflorescence treatment in both seasons. P2 (6 strands/inflorescence) showed the highest values of bunch weight, fruit weight and flesh weight. Moreover, fruit chemical properties were enhanced under this treatment compared to the other treatments. Based on these results, it is recommend that the optimum pollination level to improve fruit set and quality of “Hayany” date palm is 6 strands/inflorescence, under Kafr El-Sheikh conditions. | ||
