降解菌对大豆生长前期莠去津毒害作用的缓解
Alleviation Effects of Degrading Bacteria on Atrazine Toxicity in Early Stage of Soybean Growth
摘要
Abstract
Atrazine toxicity alleviation of degrading bacteria (Enterobacter sp.) was investigated by determination of growth and physiological indexes of soybean,utilizing seed germination and pot experiments in the early stage of soybean growth.The results showed that the degrading bacteria could significantly increase the germination rate,germination index,seed vigor index and α-amylase activity of soybean seeds,reduce the electrolyte extravasation and the accumulation of proline.Degradation bacteria could promote the growth of soybean seeding.After treated with bacterial solution,root development index,embryo and cotyledon weight were significantly increased compared with atrazine treatment.Test strains could effectively relieve the toxicity of atrazine.关键词
