Glufosinate is a non-selective chiral herbicide, which has been used extensively around the world. However, limited information on the enantioselectivity ofRac- and L-glufosinate against crops. In this study, the enantioselective effects on the growth, antioxidant, and targeted enzyme activities of maize seedlings of chiral glufosinate were investigated. The results showed the enantioselective growth inhibitions were observed at both 1 and 5 mg/L concentration levels.l-Glufosinate induced more growth rate reduction in shoot height and weight compared toRac-glufosinate. All of the antioxidant enzyme activities increased obviously in the leaves of maize seedlings treated by 1 mg/L of glufosinate. Superoxide dismutase (SOD) activity, catalase (CAT) activity, peroxidase (POD) activity, glutathione reductase (GR) activity, and malondialdehyde (MDA) content induced byl-glufosinate were 1.36, 1.16, 1.51, 1.65, and 1.65 times higher than those byRac-glufosinate, respectively Notably, the glutamine synthetase (GS) activity was significantly reduced to 80% and 57% in the control group at 1 mg/L treated withRac- andl-glufosinate, respectively. Our results indicated thatRac- andl-glufosinate showed the obvious enantioselectivity in the growth of maize seedlings, which has shed light on the potential enantioselective phytotoxicity of glufosinate. Data provided here will be helpful to develop the environmentally friendly herbicides.
