Alleviating effects of salicylic acid spray on stage-based growth and antioxidative defense system in two drought-stressed rice (Oryza sativa L.) cultivars
: Approximately 33% of the arable land around the world is vulnerable to drought, which is a very serious issue affecting the yield and productivity of cereal crops. Two contrasting rice ( Oryza sativa L.) genotypes, HTT-138 (drought tolerant) and (HTT-39 drought-sensitive), under various levels of water treatments, i.e. control flooded (CF) as recommended for rice (control), control saturated (CS) 100% field capacity (FC), 80% FC, and 60% FC without or with foliar spray (100 mg L –1 ) of salicylic acid (SA) evaluated to enhance the yield for food security. The results showed that leaf gas exchange parameters, water use efficiency and water related parameters reduced under all levels of water deficient conditions. Drought stress increased oxidative stress (superoxide anions and hydrogen peroxide) and decreased after foliar spray of SA due to enhancement in antioxidant activity (catalase, ascorbate peroxidase, peroxidase, superoxide dismutase). Ascorbic acid
