Akhaseeb reagent-This study was carried out in private orchard at Abo Basra.

To investigate the causes of pollen metaxenic effects for some pollen date palm male by relationship to endogenous hormones and some physical fruit characteristics.

The date palm cv.

Hillawi was pollinated by tow pollen source ( Hukri Adi and Ghannami Akder ), the fruit had spread by water extracted of pollen ( Hukri Adi and Ghannami Akder ) at concretion ( 2 gm / L) and NAA ( 25 ppm ) at 30 and 45 days after pollinated.

The result showed the pollen Hukri Adi was a significant effect in fruit sizes and endogenous hormone levels( IAA, GA3.

Cytokinin ) comparison with fruit result from Ghanami Akdar pollen, the treatment of NAA was a significant effect in fruit sizes and endogenous hormone levels ( IAA, GA3.

Cytokinin ), whereas NAA gave a lowest levels in ABA but the pollen extraction of Hukri Adi had no significant effect with fruit produced by Ghannami Akdar with spry by NAA.

The study was concluded the metaxenic effect of pollen source ( Hukri Adi ) may be result from pollen promoter substance contents in pollen grains.
