| Abstract | ||
| This study was carried out on date palm fruit cv. Hillawi at Abuo- Alkaseeb – Basrah during the growth season of 2009 to test the hypotheses of Swingle ," that the metaxenic effect is related to endogenous hormone product by the embryo or endosperm" . The result ,showed that changed in endogenous hormones (cytokinins and abscisic acid) correlated with their physiologic role.The levels of cytokinins were high during earliest stages of fruit growth which coincide with cell division stage, but there were a raped decline in level of this endogenous hormone as the fruit entered the stage of physiological maturity (Khalal stage), but heighest level in ABA. The pollen source had a significant effect on hormone level , with fruit produced by Khikri Adi pollen had the highest cytokinin . Fruit produced by Ghannami Akder had the highest level of ABA as compared with the fruit produced by KhiKri Adi .The result obtained in the present work , gave a strong support to Swingle's hypothesis of Metaxenia | ||
