Lolium multiflorum is widely used to remediate pollutant residues in the environment. The tolerance of plants to pollutants is a key factor affecting the phytoremediation effect and limiting plant application. In this study, 13 herbicides including alachlor, butachlor, metolachlor, imazamox, atrazine, prometryn, fomesafen, quinclorac, flumetsulam, clomazone, isoxaflutole, pendimethalin, and 2,4-D with long residual time and serious environmental toxicity were used for evaluation of the tolerance ability of L. multiflorum. The seed germination and plant growth, as well as physiological characteristics of L. multiflorum after exposure to different herbicides concentrations were explored. The membership function value method was used to analyze the tolerance of L. multiflorum to different herbicides. Results revealed that low-concentration herbicides promoted the seed germination and plant growth of L. multiflorum, while high-concentration herbicides performed an inhibitory effect. The antioxidant enzyme activities in plants were increased under herbicide treatment. L. multiflorum had strong tolerance to quinclorac and weak tolerance to imazamox, atrazine, clomazone, and isoxaflutole.
