摘　　要：在白花泡桐种子萌发的不同时段、采用不同浓度的甲基磺酸甲酯对种子进行不同时间浸泡处理,记录种子发芽率,测定各处理种苗的内源激素含量。结果表明:在3种因素中,不同时段的处理对种子发芽率和GA含量影响极显著;浸泡时间对ABA含量影响显著;而3种因素对种子芽内的IAA含量、ZR含量影响均不显著;GA含量与种子的发芽率成正相关。In lab teat in 2004, the Pawlownia fortunei seed was soaked with different concentrations of methyl methanesulfonate for different time in different time interval of seed sprouting, the seed germination rate was recorded and the endogenous contents in all simples were determined. The variance analyses show that the different time interval has a specially significant effect on GA content in seed germination. The soaking time has significant effect on ABA content. IAA and ZR content in seed germination are not sensitive to above three factors. The GA content positively correlated with seed germination.
