Abstract: The effect of manganese (Mn) on root activity, contents of proline, protein and malonaldehyde in leaves were studied using method of water culture. The results showed that appropriate Mn increased root activities of soybean and decreased contents of proline, protein and malonaldehyde in leaves, but the result was reversed under high Mn. There was difference in the response of soybean to Mn between Zhechun No.2 soybean and Zhechun No.3 soybean, and Zhechun No.3 was more sensitive than Zhechun No.2.

Key words: manganese, soybean, physiological characteristics

摘要： 利用水培法研究锰对浙春2号和浙春3号大豆根系活力及叶片脯氨酸、丙二醛和蛋白质的影响。结果表明,适量锰处理可提高大豆根系活力,降低叶片中脯氨酸、蛋白质和丙二醛含量;锰过量,不利于大豆生长。两个大豆品种对锰的反应有差异,浙春3号对锰的敏感性大于浙春2号。
