Ever growing human needs, industrial explosion,
fast paced and rapid depletion of fossil fuels are theof primary concern forin the globalenergy crisis all over the world.. There is an immediate demand for alternatealternative renewable energy sources. Biodiesel made from vegetable and animal fats is among one of thethese alternatives [1 ]. More] and more than 95% of biodiesel is made from edible oils and food crops. UsingUse of agricultural land for producing the production of biofuel plants affected negatively impacted the world food supply, resulting in a food crisis in many countries. In contrast, using use of marginal lands for growing biofuel plants is an economical and probable viable solution to the this problem. Many MarginalHowever, many marginal lands are highly saline and poor in nutrients. SaltHigh salinity affects approximately 75 million hectares ofarable land in the world and most of most crops are sensitive to salt stress at during all stages of plant development . Salinity induces osmotic stress and oxidative stress resulting in alteration in of plant metabolism including reduced water potentials, ionic imbalance and specific ion toxicity [3, 4]. Plants have evolved strategies to cope with salinity and different plants vary greatly in their tolerance. Among these strategies, some plants are able to effectively respond to salt stress and alter by altering their germination and growth rates[5, 6]. Tolerant plants adapt to saline conditions by accumulating osmolytes, organic, and inorganic solutes. Salt -induced oxidative stress increases reactive oxygen species leads to increased levels of reactive oxygen species(ROS), such as superoxide (O2-.) [7, 8], malondialdehyde (MDA) accumulation, and membrane leakage . Enzymatic and non-enzymatic antioxidants anti-oxidants play an important role in protecting plants against oxidative stress damages-induced damage through detoxification of reactive oxygen species (ROS ) ,, protection of membrane integrity, and stabilization of enzymes or proteins [10,11].
