A major result of abiotic stress is the excessive production of Reactive Oxygen Species (ROS) which are capable of damaging all types of cellular structures. Whereas well - ordered redox homeostasis act under normal conditions to keep them from accumulating to damaging levels, they are overwhelmed under sub optimal conditions. This review considers the role of plants antioxidant defense system in managing oxidative stress and shows clearly that when confronted with stressful conditions such as drought and salinity the plants antioxidant defense machinery becomes inadequate and must be supported to be able to rise up to the stress challenge. The paper discussed the exogenous application of a variety of substances as a veritable source of such assistance, showing how their supply ameliorate stress effect and enhance crop productivity.
Key words: Oxidative stress, antioxidants, Compatible osmolites, hormones, exogenous application.
