Abstract
[Aims] This investigation is to determine the alexipharmic effect and mechanism of 1,8-naphthalic anhydride(NA) protecting sorghum from phytotoxicity of imazethapyr.[Methods] The alexipharmic effect and mechanism of 1,8naphthalic anhydride(NA) to the imazethapyr residue in soil was studied with simulated method,using potted sorghum as bioassay material.[Results] In this experiment the dosage of imazethapyr is 25 g a.i./ha.The results showed that imazethapyr could be an injury to sorghum seedlings.NA could reduce the injury effects of imazethapyr to sorghum.The height and fresh weight of sorghum seedling treated with NA + imazethapyr were obviously higher than those of imazethapyr treatments.NA and imazethapyr could induce the change of amino acid content in sorghum seedlings.This change can be considered as one of the factors of NA detoxification of imazethapyr.NA and imazethapyr affect the content of glutathione(GSH) and the activity of glutathione-S-transferase(GSTs) differently in sorghum seedlings.GSH content and GSTs activity obviously increased in sorghum seedlings.[Conclusions] It indicated that NA can reduce the injury of imazethapyr to sorghum and the alexipharmic mechanism of NA reducing the phytotoxicity of imazethapyr to sorghum was the change of some amino acid content and the increase of GSTs activity.
