The decrease of MDA contents was concomitant with the increase of catalase (CAT) and Ascorbate peroxidase (APX) activities in GB-treated plants under all water treatments compared with GB-untreated plants which suggested GB application potentially up-regulated antioxidant activities. Consequently, the increase of antioxidant activities was adequate to deflate lipid oxidation by mitigate MDA contents. In conclusion, the exogenous application of GB positively affected physiological, yield and biochemical variables of rice plants under low water input condition which was showed by the positive interactions between both treatments.

| summary | Water stress massively affected the growth and production of rice by disrupting physiological functions and triggered the production of reactive oxygen species (ROS) resulting in oxidative damage to the plants, hence reduced yield production. In this present study, we aimed to determine the effects of exogenous GB in improving physiology, and yield components variables as well as biochemical responses of rice plants under different soil water regimes. We also intended to determine the interaction between the different soil water regimes and concentrations of GB. In the first experiment, four water regimes (W1: field capacity, W2: saturated condition, W3: 1 cm flooding condition and W4: 5 cm flooding condition) were applied to the plants with and without GB at three different concentrations (B0: 0 mM, B1: 50 mM and B2: 100 mM) to elucidate the effects of GB on both physiology and yield variables. In the second experiment, the enzymatic antioxidants activity including catalase (CAT) and ascorbate peroxidase (APX) together with malondialdehyde (MDA) contents were measured spectrophotometrically based on their known specific wavelengths using the same treatments as the first experiment to justify the effects of GB on biochemical processes within plants. The rice plants which were grown in pot were arranged as factorial completely randomized design (CRD) in both experiments with three and five replications for physiological and biochemical as well as yield variables respectively. GB-treated plants with 50 mM and 100 mM concentrations significantly increased physiological variables of rice plants compared to GB-untreated plants. The rice plants that were grown under W1 and W2 treated with GB manifested more positive results compared to flooding condition, W3 and W4.
