Effect of Selenium on the Response of the Active Oxygen Scavenging System in the Leaves of Paddy Rice under the Stress of Herbicide
硒对除草剂胁迫下水稻幼苗活性氧清除系统响应的作用

The effects of selenium on the protection system in the leaves of paddy rice were studied under the stress of herbicide mefenacet. The results showed that selenium could cause increase of the height and root length, enhanced the contents of protein, glutathione(GSH) and the activities of antioxidant enzyme, leading to decreased level of activated oxygen and malondialdehyde(MDA), slowering the autoxidation rate. All these could alleviate the harmful effect of mefenacet on paddy rice. The paired t test results showed that the effect of selenium on the response of the active oxygen scavenging system were significant.
