Potential Impact of Marine Algal Extracts on the Growth and Metabolic Activities of Salinity Stressed Wheat Seedlings

Wael M. Ibrahim

Abstract:
Background: Salinization of land is one of the most widely serious problems in agriculture production. Using of exogenous bioactive substances not only improve the biological properties of several agricultural crops but also help in promoting their yield in saline environments. Methodology: In this study, the potential effect of crude extract of five marine algal species on the germination, growth and some enzymatic activities of salinity stressed wheat seedlings were investigated. Results: Increasing of salinity showed a sharp inhibition on the germination percent and seedling growth criteria of wheat seedlings. Algal presoaking of salinity stressed grains demonstrated a highly significant enhancement in the percentage of seed germination and growth parameters especially with the extract of red alga Laurencia obtusa. A marked promotion in the activity of the antioxidant enzymes, catalase (CAT) and superoxide dismutase (SOD) was recorded in the salinity stressed plants. The occurrence of bioactive compounds in algal extracts such as flavonoids, proline, ascorbic acid, citric acid and plant hormones could potentially participate in the alleviation of salinity stress. Conclusion: The present study confirmed the presoaking technique of marine algal extract is an effective technology in solving one of the greatest economic problems in agriculture.
