【摘要】 以梭梭(H.persicum)种子为研究材料,用不同浓度的聚乙二醇(PEG)浸种处理,促其在常温(20~25℃)及低温(10~15℃)下发芽,通过对发芽率及过氧化物酶(POD)和过氧化氢酶(CAT)的活性测定。结果显示,常温25%PEG引发下,其种子萌发效果最为明显;梭梭幼苗CAT和POD在不同处理下其酶活性存在着显著的差异,说明不同处理的梭梭幼苗在抗逆性上的程度是不同的。更多还原

【Abstract】 The research is based on the H.persicum seeds which are dipped into the PEG of various concentrate.Later we make them germinate in the degree temperature of 20-25,10-15.From the mensuration of the rate of germination,the activity of POD and CAT,we can draw the conclusion that in the environment of 25%PEG and 20-25℃ the seeds germinate become more easier.The activity of CAT and POD is different with different environment,from which we can see the H.persicum seeds have different stress resistance under different conditions.更多还原
