Abstract
The present study was carried out during the growth season of 2018 on date palm trees phoenix dactylifera L. Al-Shwethy cv. In a private orchard at Al-Rifai district in the north of Thi-Qar city. To investigate the effect of different pollen grain (green ghannami, khikri and elected seed strain), as well as, chitosan treatment (0%, 1% and 2%) on some physiological and enzymatic characteristics. The results can be summarized as follows: 1. The different source of pollen grain and chitosan treatments had a significant effect on physiological and enzymatic properties of fruit at the Rutab stage 2. The seed strain and green ghannami treatments showed high levels of the set and maturity percentage of fruits, also the activity of invertase and cellulase enzymes, and the lowest percentage of fruits dropping compared to control 3. The treatment of chitosan at a concentration of (2%) had a positive significant effect on the set and maturity percentage of fruits, while the lowest percentage of fruits dropping was examined in above treatment compare to the control treatment, additionally the treatment of chitosan at same concentration showed highest increase activity of the invertase and cellulase enzymes in the khalal stage. .
