通过盆栽试验，研究施硒对3个花生品种营养生长、生理特性及品质的影响。结果表明：土壤基施硒3 mg／kg，花育25、山花7号和山花8号在开花下针期主茎高、分枝数、根干重、叶绿素a、叶绿素b、叶绿素a＋b都高于对照，而类胡萝卜素、叶绿素a／b都低于对照；结荚期叶片SOD、POD、CAT活性，可溶性蛋白含量均显著高于对照。因此，土壤施硒有利于花生植株生理代谢，促进植株生长发育。
通過盆栽試驗，研究施硒對3箇花生品種營養生長、生理特性及品質的影響。結果錶明：土壤基施硒3 mg／kg，花育25、山花7號和山花8號在開花下針期主莖高、分枝數、根榦重、葉綠素a、葉綠素b、葉綠素a＋b都高于對照，而類鬍蘿蔔素、葉綠素a／b都低于對照；結莢期葉片SOD、POD、CAT活性，可溶性蛋白含量均顯著高于對照。因此，土壤施硒有利于花生植株生理代謝，促進植株生長髮育。

The effects of applying selenium on vegetative growth, physiological characteristics and quality of three peanut varieties, Huayu 25, Shanhua 7 and Shanhua 8, were studied through pot experiment.The re-sults showed that basal application of 3 mg/kg selenium, the main stem height, branch number, root dry weight, chlorophyll a, chlorophyll b and chlorophyll a+b of three peanut varieties were all higher than those of control during flowering and pegging stage, while the carotenoids, chlorophyll a/b were lower than those of control;the SOD, POD, CAT activities and soluble protein content in leaves of three peanut varieties were significantly higher than those of control at pot-setting stage.Therefore, applying selenium was conducive to physiological metabolism, growth and development of peanut.
