【 摘 要 】

The effects of accumulator plant straw on the osmotic adjustment substances and malondialdehyde content of lettuce under cadmium stress were studied by pot experiment. The results showed that the content of malondialdehyde in the leaves of lettuce after the application of accumulator plants, including Siegesbeckia orientalis, Conyza canadensis and Eclipta prostrata decreased by 29.26%, 29.74% and 30.55%, the content of soluble sugar increased by 2.13%, 15.00% and 19.15%, and the content of proline increased by 119.42%, 88.11% and 68.31%, respectively. Therefore, the application of S. orientalis straw can reduce the malondialdehyde content in lettuce leaves, increase the content of soluble sugar and proline, and enhance the resistance of lettuce.
