L, ashrasi cultivar, the experiment included 9 treatments that resulted from the overlap of two factors. Spraying with 200 mg L⁻1 2G glutamine acid was sprayed one day before pollination and before and after fruit setting. The pollen variety had a significant effect on most of the physical traits. The pollen variety had a significant effect on most of the chemical characteristics, as the mixed pollen variety (Al-Fahal Dakl+Male Yellow) excelled in recording the best results for the characteristic of the leaf content of nitrogen 2.08%, the content of the leaves of phosphorus 0.52%, the content of the leaves of potassium 2.37%, the content of Total chlorophyll 15.89 mg gm⁻1 fresh weight. Spraying with glutamic had a significant effect on most traits, as spraying at a concentration of 200 mg L⁻1 was superior in recording the best results for the characteristic of leaf content of nitrogen 2.04%, content of potassium 2.34%, leaf content total chlorophyll and 15.26 mg L gm⁻1 fresh weight, that the bilateral interaction between the pollen variety and spraying with glutamic lion significantly affected most of the chemical properties, as the treatment of the bilateral interaction between spraying with a concentration of 200 mg L⁻1 and the mixed pollen variety (Al-Fahal Dakl+Al-Fahal Yellow) excelled in recording the best results. As for the content of the leaves of nitrogen 2.11%, the content of the leaves of phosphorous 0.55%, the content of the leaves of potassium %.
