الملخص EN

The present study has been conducted during the growing season of 2018 at tree Date palm (Phoenix dactylifera L.) at a private orchard at center of Thi-Qar Govermorate the study evaluate the effect some of thing female Khadrawi ,Shwethee and Sayer cultivars with spraying the tree with the-growth catalyst Agazone (0 , 3 , 6 ML.L-1 ) in some chemical (Total sold material solute , Total acidty that able to equilty the Finol content , the activity of Invetase enzyme.

We can summavze the The cultivars Shwethee significantly superior to take off increased in results as follow : percentage of total sold material solute as ( 66.67 , 77.89 )% , and a less percentage in total acidity that able to a quinte ( 0.460 , 0.334)% and phinol content (0.166 , 0.099)% in a grade of khalaal and Rutab and increased of activity of enzyme invertase in stage of khalaal (37.53) gram/unit/minute and less percentage in stage of Rutab (11.35 ) gm/unit/minute cultivars Khadrawi and sayer.

write treatment the-growth catalyst Agazone 6 ML.L-1 significantly superior of total sold material solute as ( 68.00 , 78.00 ) %, and a less percentage in total acidity that able to a quinte ( 0.458 , 0.338 )% and phinol content (0.172 , 0.088 )% in a grade of khalaal and Rutab and increased of activity of enzyme invertase in stage of khalaal ( 37.68 ) gm/unit/minute and less percentage in stage of Rutab ( 11.37 )gm/unit/minute .

For effect interactions clear as superior effect cuple (cultivars Shwethee and 6 ML.L-1 Agazone ) significantly increased in total sold material solute , and a less percentage in total acidity that able to a quinte and phinol content and increased of activity of enzyme invertase in stage of khalaal ( 38.96 ) gm/unit/minute and less percentage in stage of Rutab ( 10.02 )gm / unit / minute.
