Influence of Brassinosteroids on Wheat Plant (Triticum aestivum L.) Production under Salinity Stress Conditions I- Growth Parameters and Photosynthetic Pigments

Abstract

Green house experiment was conducted to alleviate the effect of irrigating saline water at (0.2000, 4000 and 6000 ppm NaCl solution) by using foliar spray of BRs 28-homoBL at levels of 50, 100 and 200 mg/L on wheat plant (triticum aestivum L.). Brassinosteroids play an important role in growth, metabolic activities and productivity of wheat plants. BRs significantly increase all the growth parameters, photosynthetic pigments as compared with the untreated control plant. Foliar application of BRs also increased yield and yield attributes of treated plants and significantly overcome the depressive effect of saline irrigation water at all levels on crop productivity and photosynthetic pigments.
