SEASONAL VARIATIONS OF ASH CONTENT OF THE HALOPHYTE ZYGOPHYLLUM QATARENSE HADIDI FROM SALINE AND NON-SALINE HABITATS IN BAHRAIN J. A. ABBAS*
Abstract:
The roots and leaves of the halophytic plant Zygophyllum qatarense
Hadidi from saline and non-saline habitats in Bahrain island were analysed
for their ash content during four seasons: winter, spring, summer and
fall. Ash content of leaves was higher than that in the roots from the
two habitats. Statistical analyses of the results showed significant
seasonal differences in the ash content in both roots and leaves in
each of the two habitats. Comparison between the ash content of leaves
from the two habitats showed no significant difference between the averages
for the leaves in all seasons except in the spring. Root comparisons
showed significant differences between the two habitats in all seasons
except in the fall. The results demonstrated that the change in soil
salinity is reflected, at least in some seasons, in the ash content
of Z. qatarense. The only significant difference in the ash content
between the leaves of the two habitats was during spring. However, the
only nonsignificant difference in the ash content between the roots
of the two habitats was during the fall.
