الملخص EN

The current study has been conducted during the cultivation season of 2011 at the labs of Date Palm Research Centre, Basra University to evaluate the damage effect of the physiological disorder Abu- khshem of the Hilawi date palm cultivar .

The experiments has been done on two different stage of date palm fruits:Al-Rattab and tamer stages.

The results of this study showed that the physiological damage structure of Abu-khshem decreased on the anatomy the structure of fruits, especially on the thickness of the inner Mesocarp area.

It was evident from the resulte the significant effect of Abukhshem decreased on the thickness of inner Mesocarp which decreased significantn from 3.38mm in Hilawi fruit before the damage and reached to 1.99 mm in the affected fruits Similar results were revealed with the tannins areas before and after the damage which caused by Abu – Khshem disorder , the thickness was 0.61 mm before the damage and reached 0.30 mm in the affected fruits.

The analysis of the results did not show any significant differences for the following anatomical thickness of exocarp, thickness of stone cells layer and thickness of vascular bundle diameter parameters before and after Abu – Khshem damage of Hilawi damage.

Also the experiment recorded in both Date Palm fruits two types of sclerenchyma cells in exocarp stone cells and bone shaped sclerieds.
