Sodium Alginate Stimulates Growth and Metabolism in Shoots of Corchorus olitorius, Vicia faba, and Zea mays Through the Vegetative Stages

Abstract

In recent studies, sodium alginate (SA) has mainly been a plant growth promoter for many plants and crops as a novel bio stimulating materials for increasing plant growth under various conditions. Pot testing was done to examine the impacts of various levels of SA (25, 50 and 100 ppm) on the growth and physiological activities of Corchorus olitorius (molokhya), Vicia faba (faba bean) and Zea mays (corn) plants in two vegetative stages after 10 and 40 days from sowing. Treatment with different SA concentrations improved significantly the physiological characters of the used plants. The data indicated that the used SA concentrations increased photosynthetic pigments, carbohydrate contents, nitrogen contents, antioxidant enzymes and overall protein significantly as compared to control values.
