| Abstract | ||
| Summery This study was conducted in a private orchards in Shatt-al- Arab region Basrah during the growing season 2010 to study some of anatomical changes of seeded and parthenocarpic fruits of the date palm ( Phoenix dactylifera L.) cv. Hillawi through the stages of growth and development. The results showed that seeded and parthenocarpic fruits of the date palm CV.Hillawi have single sigmoid growth curve. which was characterized by three phases. a phase of slow growth and the stage of rapid growth. and maturation at which the fruits seeded reached their maximum fresh weight ( 16th week after pollination).the parthenocarpic fruits were slow increase in the rate of weight until when coming into Kalal ( 21th week after pollination) it reached the maximum fresh to it. observed over parthenocarpic fruits had a significant effect on thickness of the layer exocarp, the layer cutical where recorded and the length of tannins cells where recorded (143, 7.11, 100.4) micrometers respectively , whil the seeded fruits had a significant on effect thickness of the tannins cells layers amounting to (0.505)mm2 and length of epidermis cells layers where recorded (12.75) micrometers, Also results showed a significant difference between periods of growth from the fourth week until the seventeenth week after pollination. As well as the existence of a significant of the overlap between the fruit type and growth periods ( week after pollination) for all the studied anatomical changes. | ||
