乙草胺对水稻的伤害及CGA_(123407)对其伤害的保护作用

Preliminary Study on the Effect of Protectant CGA_(123407) in Protecting Rice Seedlings from Injury by Acetochlor

乙草胺用于水稻田易引起药害 ,该实验用适当浓度的CGA12 3 40 7和乙草胺同时施用 ,能部分解除乙草胺对水稻幼苗的伤害 对水稻幼苗保护酶系统活性的测定表明 。

Rice was very sensitive to acetochlor. Rice seedlings were injured when acetochlor was used in rice field. But acetochlor showed less phytotoxicity to rice seedling when used in combination with protectant CGA 123407 . The activities of endogenous protective enzymes, superoxide dismutose (SOD), peroxidase (POD) and catalase (CAT) were studied, and the results showed that the effect on the activities of endogenous protective enzymes was not the main injury mechanism of acetochlor.
