| Abstract | ||
| The present research was carried out in a private orchard in Abo-Alkaseeb–Basrah during growing season (2009) to study pollens effect of male cultivars (Khikri Adi and Ghannami Akhder), to study some fruit characteristics(fruit weight, fruit volume and TSS), Production characteristics(fruit set, bunch weight and tree production) This study was carried out for study the histological change of date palm fruit cv. Hillawi during growth and ripening and effected by pollen source. The results showed the fruit produced by Khikri Adi pollen entered the ripening phase (R utab stage) at the end of 14th week from pollination, whereas fruit produced by Ghannami Akdar pollen reached the ripening phase by the end of 15th week. The pollen source had a significant effect on percentage fruit ripening, with fruits produced by Khiri pollen had the highest ripening percentage as compared to fruits produced by Ghannami pollen. The pollen source also had a signisicant effect on bunch weight and the tree yield, with trees pollinated with khikri pollen had highest bunch weight and tree yield as compared to Ghannami pollen. The various layers of date palm fruit, as well as changes in cell length,volume, and the thickness of the inner and outer mesocarp layers of the fruit. The results showed, that fruit growth was due to the increase of cell volume, especially during the phase of rapid growth rate, as the cell volume increased dramatically, which coincided with the increase of fruit volume. Most of fruit growth, was due to the increase of cell diameter at the innermesocarp as compared with outermesocarp. The results, also showed, that there was a significant effect of the pollen source on the anatomical characteristics of the fruit, with respect to cell volume and diameter, as well as the thickness of the innermesocarp and outermesocarp layers. | ||
