地乐胺（dibutralin）可降低大豆幼苗根腐病的发病率和严重度，可使大豆幼苗的RNA含量和叶部蛋白质含量增加，RNA酶活性提高，对蛋白酶的活性无影响，这说明地乐胺可诱发某些应激蛋白的产生。另外DNA含量和根部蛋白质含量略减少，幼苗体内IAA,GA,Z，ABA4种激素的含量有不同程度的变化。这些变化都对大豆根腐病的发生有不同程度的影响。
The results showed that dibutralin could reduce the incidence and severity of root rot in soybean seedlings, increase the RNA content and leaf protein content of soybean seedlings, increase RNase activity and had no effect on protease activity, Amines can induce the production of certain stress proteins. In addition, the content of DNA and the content of protein in root decreased slightly, and the contents of IAA, GA, Z and ABA in seedlings changed to some extent. These changes have different degrees of impact on the occurrence of soybean root rot.
