| 摘 要： | 选取3个含有Bt基因甘蔗株系进行光合系统和抗氧化系统的研究.转基因株系的净光合速率、胞间二氧化碳浓度、气孔导度、蒸腾速率和对照相比没有明显的差异；转基因株系中的SOD、POD、CAT和MDA的变化较小.结果表明:Bt基因的插入导致部分甘蔗的生理指标发生变化,不同的株系生理变化不一致. |

| Abstract: | The photosynthetic system and antioxidant systems in three Bt transgenic sugarcane strains were studied.The changes of net photosynthetic rate,stomatal conductance,transpiration rate and intercellular CO2 concentration in the leaves of Bt transgenic sugarcane strains were not obviously different with non-transgenic sugarcane strains(ROC20).The SOD,POD,CAT activity and MDA content in transgenic sugarcane strains had a little change.The results showed that Bt gene in sugarcane partially led to the change of p... |
