Assessment of Cyanobacteria and Tryptophan role in the Alleviation of the Toxic Action of Brominal Herbicide on Wheat Plants

Abstract Cyanobacteria like Arthrospira platensis and Nostoc muscorum are known to be beneficial for plant development. They can improve growth, yield, proximate content (protein carbohydrate), stimulate tolerance abiotic stresses herbicides. In the present study, impacts of brominal herbicide (Bh) alone or in combination with natural cyanobacterial synthetic tryptophan treatments were investigated on morphological physiological parameters wheat plants. The Bh treatment caused a reduction all estimated could significantly increase length, fresh dry weights, yield (spike spike weight, number spikes per plant, grains spike, weight 1000 grains, productivity). addition, pigments, carbohydrates, protein was also reduced response treatment, while antioxidant enzyme activity lipid peroxidation increased. Priming aqueous extract before cultivation reversed toxic effects application, amplified extra ability, decreased Finally, as priming being sown soil should help strengthen defense systems tolerate adverse species-specific upon application.
