摘　　要：研究卫星搭载对白三叶种子萌发,植株生长及生理特性方面的影响。结果表明:卫星搭载的白三叶种子发芽势、发芽指数和芽长显著高于对照,根长、根芽比低于对照,且差异显著(P<0.05);卫星搭载对株高无显著影响,对叶片大小有一定抑制作用,但促进白三叶的分枝;卫星搭载白三叶幼苗的POD、CAT、SOD活性较对照均有提高,其中POD与对照差异显著(P<0.05)。The seed germination,growth and physiological features of white clover（Trifolium repens）carried by recoverable satellite were studied.The results showed that the germination vigor,germination index and shoot length were significantly higher than the control,but root length and bud ratio were significantly lower.Satellite carrying did not show significant impact on plant height,and it decreased the leaf size and promoted the branching.The active of POD,CAT and SOD was improved,in which,the difference of POD was significant compared with the control.
