Abstract
Algal extract showed a significant positive
influence either alone or combined with different salt concentrations, on the
lengths of the shoot and root, as well as the fresh and dry weight of all the
seedlings subjected to the study. The promoting effect of algal extract extend
to photosynthetic pigments (chl a, b and carotenoids) was also observed for all
salt-stressed seedlings. It was observed that the activity of the enzyme
superoxide dismutase (SOD) increased in seedlings treated with salt compared to
the stressed seedlings that interacted with algal extract (by 2.5% at both salt
concentrations in bean, 2.6% at low salt concentration and 1.15 at high
concentration in wheat and 5% at low and 8.4% at high salt concentration in
corn). This was also confirmed by the rate of free radical activity as well as
the amount of proline in the shoots of all crop seedlings subject to the study.
Hence, the role of algae extracts in alleviating the harmful effect of sodium
chloride salt on crop seedlings is clear.
