| 摘 要： | 在营养液培养条件下以普通结结瘤大豆Ｂｒａｇｇｃｖ．「Ｇｌｙｃｉｎｅｍａｘ（Ｌ．）Ｍｅｒｒ」及其超结瘤突变体ｎｔｓ３８２为实验材料，运用光学显微方法研究了硼对大豆根瘤结构的影响，并测定了根瘤固氮酶活性结果表明，缺硼使根瘤结构受到严重破坏，并使固氮酶活性显著下降，缺硼使根瘤结构受到破坏是导致固氮酶活性下降的可能原因。

| Abstract: | ffects of boron deficiency on structure and nitrogenase activity of soybean plants Glycine max (L.) Merr] were studied.Examination of structures of nodules from the plants grown in nutrient solution without boron showed that first,the number of the infected cells decreased;Secondly,Vacuoles in infected cells were much more than control;and the third,the middle of nodules was damaged markedly.The nitrogenase activity of nodules decreased markedly.The destroy of the structures from nodules is responsible for this decrease of the nitrogenase activity. |

| Keywords: | boron deficiency structure of nodule nitrogenase activity soybean ( Glycine max (L ) Merr ) |
