Abstract
:
ABSTRACT. This research was conducted on two date palm cultivars namely Ghur and Sukariat Yunbo at the Agriculturral Research Station of king Abdulaziz University in Hada Al-Sham for two years (1996 and 1997).The seasonal changes in physical and chemical properties of fruits was studied during different growth stages, in order to determine the fruit ripening and the appropriate time for picking. Fruit growth of both cultivars was characterized by a rapid increase in fruit weight , flesh and seed weight. The maximum fruit and flesh weight was obtained after 19 weeks from pollination in both cultivars. Meanwhile, the seed gained its maximum weight after 18, 16 weeks from pollination for Ghur and Sukariat Yunbo cultivars, respectively. There was a decrease in flesh/seed ratio during the periods 14th through 16th and 12th through 14th weeks from pollination in Ghur and Sukariat Yunbo cultivars, respectively. This may be attributed to that the increase in percentae of seed weight was more than the increase in percentae of flesh weight. After this period, a gradual increase was noticed in the flesh/seed ratio till fruit ripening. There was a negative correlation between total soluble solids (TSS%) and moisture percentages in fruit . The TSS% reached its maximum value at the stage of fruit ripening, while the moisture percentage was at its minimum value. Acidity percentage showed up and down fluctuations during the process of fruit growth till it reached its minimum value at ripening stage in both cultivars
