摘　　要：本试验研究了水培和土培条件下，硒对大豆植株体内谷胱甘肽过氧化物酶（ＧＳＨ－Ｐｘ）活性的影响。结果表明，在水培和土培试验中，硒都能显著地提高大豆植株体内ＧＳＨ－Ｐｘ的活性，方差分析结果分别为Ｆ＝５８．６７＊＊和Ｆ＝１１．３８＊＊，在水培试验中，０．０５ｍｇＳｅＬ－１处理的植株干物重较对照增加３５．０１％，Ｆ＝８．３３＊＊，在土培试验中，１．６４ｍｇＳｅｐｏｔ－１处理明显地提高大豆对红蜘蛛的抗性，使产量较对照增加３０．００％，Ｆ＝６．６８＊。Pot and solution culture experiments were conducted to study the effects of selenium on glutathione peroxidase (GSH-Px) activity in soybean plants. Results indicated that selenium increased the GSH-Px activity in soybean plant in both pot experiment and solution culture, F=58.67 * * and F=11.38 * * respectively. In solution culture, the dry weight of soybean plant in the treatment of 0.05 mg Se L - 1 increased by 35.01% compared with that in control (no selenium), F=8.33 * *. In pot experiment, 1.64 mg Se pot - 1 increased the resistance of soybean to spider mite significantly. As a result, the soybean yield increased by 30% compared with that of control, F=6.88 * *.
