Lettuce (Lactuca sativa) is one of the most common green leafy vegetables, which is widely cultivated all over the world, but extremely sensitive to cadmium (Cd) contaminated in soil. The effects of three hyperaccumulator plants straw (Solanum nigrum, Bidens pilosa and Galinsoga parviflora) on the antioxidant enzyme activities and osmotic regulators and malondialdehyde (MDA) content under Cd stress were studied by pot culture. Compared with no straw, three kinds of hyperaccumulator straw of S. nigrum straw, B. pilosa straw and G. parviflora straw increased the content of soluble protein and proline in lettuce, the activity of peroxidase (POD) and catalase (CAT) in lettuce was also increased, and the content of MDA was decreased. The stress resistance of lettuce was improved and the toxicity of Cd to lettuce was alleviated by using three kinds of hyperaccumulator plant straw.
