Abstract
In the present study, we compared the effects of allelochemical, water stress (WS) and their combinations on seedling growth, biochemical parameters and responses of antioxidative enzymes in Triticum aestivum L. The wheat seedlings were treated with 0.5, 1.0 and 1.5 mM concentrations of benzoic acid (BA), with and without water stress. Leaf water status, photosynthetic pigments, protein content, amount of proline and activities of nitrate reductase and antioxidant enzymes were examined. Allelopathic stress resulted in reduction of seedling height. Height of water stressed seedlings greatly decreased. The combined treatments, BA + WS further decreased the seedling height. BA treatment with and without water stress caused significant reduction in dry weight of the seedlings. BA and water stress decreased relative water content, pigments and protein content. Total soluble sugar content and nitrate reductase activity were variedly affected under all treatments. Proline content and lipid peroxidation increased in treatments with BA and water stress. Activity of superoxide dismutase increased significantly ( P < 0.05) while catalase activity decreased in all treatments. Ascorbate peroxidase and guaiacol peroxidase activities were higher as compared with catalase which seems to protect wheat seedlings from oxidative stress. Water stress elevated the toxic effect of allelochemical.
