以浙江大学和加拿大渥太华大学合作培育成功的R5代B t转基因水稻纯合株系Ts5、Ts9和对照秀水11(Ts2)干种子为材料,研究了B t转基因水稻和对照秀水11幼苗过氧化氢酶、淀粉酶含量和根系活力间的差异。结果表明,在种子萌发成幼苗阶段,B t转基因水稻的淀粉酶和过氧化氢酶含量及根系活力均高于对照秀水11,由此表明B t转基因水稻幼苗的抗逆性和生长能力均高于对照秀水11。 In this study, we successfully cultivated the transgenic tobacco plants Ts5, Ts9 and control Xiushui 11 (Ts2), which were successfully combined with Zhejiang University and the University of Ottawa, Canada, to study the effects of hydrogen peroxide on Bt transgenic rice and control Xiushui 11 seedlings Differences in enzyme, amylase content and root activity. The results showed that the content of amylase and catalase and the root activity of Bt transgenic rice were higher than those of the control Xiushui 11 at seed germination stage, indicating that the resistance and growth ability of Bt transgenic rice seedlings were high 11 in the control show water.
