Abstract

This investigation was carried out during the two successive
seasons of 2006 and 2007 using 8 years old date palm trees of
Seewy" cultivar grown in clay soil located at Sinnaouris Fayoum
Governorate, Egypt. The objective of this study was to predict sex of
date palm through some leaf chemical constituents. Generally, it was
found that there are great differences in chemical constituents of
pinnae, i.e. chlorophyll a & b, total caroteniods, total anthocyanin,
total carbohydrates, total and reducing sugars, total free amino acids,
free proline, total indoles, nitrogen, crude protein, total phenols, dry
matter, ash and silicon between male and female date palm (c.v.
Seewy"). Female trees were characterized by the increase in the
concentration of chlorophyll a & b, total caroteniods, total
anthocyanin, total carbohydrates, total and reducing sugars, total free
amino acids, total indoles, nitrogen, crude protein, total phenols, dry
matter and silicon over male trees. On the contrary, male trees were
characterized by the increase in the concentration of ash and proline
over female trees.
From the obtained results , it has been concluded that female
date palm plants was characterized by high capacity to anabolism and
the accumulation of these substances resulting from these processes
and vice versa in pinnae of male date palm plants. These pinnae
chemical analysis can be used as a mean for predicting sex in date
palm plant " Seewy" cultivar.
