Enhancement of Antioxidant Enzymes Activities, Drought Stress Tolerances and Quality of Potato Plants as Response to Algal Foliar Application.

Background: Different types of environmental stress may induce several physiological, biochemical and molecular responses in several crop plants. According to a patent study, several types of low antioxidant defense compounds and the activity of various antioxidant defense enzymes are induced in plants grown under various biotic and abiotic stress factors.

Methods: In this work, the responses of potatoes plant treated with algae extract to drought stress were examined by evaluating the crop yield of tuber, cellular biological compounds (total carbohydrates and proteins), mineral composition and enzyme and non-enzyme antioxidant systems and total oxidative compounds.
