Resumo: 	ABSTRACT: Abiotic stresses and poor biomass accumulation are chief constraints to accomplish potential yield in Leymus chinensis. An experiment was conducted to improve biomass and correlation of biomass accumulating attributes with photosynthetic pigments, osmotic substances and antioxidants under foliar application of different plant growth substances. The experiment was conducted at inner Mongolia Xilinguole, China, using a Randomized Complete Block Design and 5 replications. The treatments consisted of water (control); BA5 = application of BA (6-benzylaminopurine) at 5 mg L-1; BA25 = application of BA at 25 mg L-1; BA50 = application of BA at 50 mg L-1; BR0.02 = application of BR (brassinosteroid) at 0.02 g L-1; BR0.2 = application of BR at 0.2 mg L 1; BR2 = application of BR at 2 mg L-1; GA10 = application of GA (gibberellic acid) at 10 mg L-1; GA50 = application of GA at 50 mg L-1 and GA100 = application of GA at 100 mg L-1. Application of all plant growth substances significantly improved biomass, osmotic adjustments, photosynthetic pigments and antioxidant activities compared to control. However, the most promising results were found with 0.2 mg L-1 BR. The highest chlorophyll a/b, glutathione and ascorbate peroxidase activities were recorded with 25 mg L-1 BA. Conclusively, 25 mg L-1 BA, 0.2 mg L-1 BR and 10 mg L-1 GA exhibited more promising results than other concentrations for the evaluated attributes.
