This study was carried out in Date Palm Research Center /Basrah University During cultivation season 2004, to evaluate invertase enzyme activity and sugars content during the growth and maturation stages in date palm fruits Cvs.

Khasab (Chemri, Khalal and Rutab).

The result showed that the high enzymatic activity was found in khalal stage was (444.36) (u/kg date) , while the lower enzyme activity was found in chemri stage which was (204.54)(u/kg date).The fruit in Rutab stage contained a high percentage of reducing sugar where was (49.24)and a lowest contained of reducing sugar recorded in Chemri stage was (13.87).

Khalal stage contained a high percentage of sucrose (48.38) while the Rutab and Chemri stages had no significant difference than in sucrose content.
