Abstract :

Drought stress is one of the main environmental factor that causes oxidative damage and adversely affect plant growth and productivity. Strategies to minimize oxidative damage are a universal feature of plant defense responses. Plant growth regulators have antioxidative characteristic that can decrease drought effect. An attempt have been made to identify the response of PGRs like SA (salicylic acid), Putrescine, GABA (Gamma amino butyric acid) and Abscisic acid on ascorbate peroxidase, guaicol peroxidase and IIA oxidase activities of medicinally important oil yielding plant Simarouba glauca DC. under water stress conditions. Increased levels of ascorbate peroxidase, guaiacol peroxidase and IIA oxidase activity were noticed in stressed plants as compared to control plants. Exogenous applications of these PGRs also showed increase in the activities of these antioxidant enzymes as compared to unsprayed stressed plants. These results indicate that SA, Putrescine, GABA and Abscisic acid plays a vital role in drought tolerance by minimizing oxidative damage.
