Turning a c3 plant into a c4 one , though , is trickier than conferring flood resistance , since it involves wholesale changes in anatomy 不过，将c3植物转化成c4植物由于涉及无数的结构变化，因此比培育抗涝品种要更为复杂。

5 . when vetiver was flooded , cat activities increased greatly and mda content rose slightly while sod activities and the electrolyte leakage have no obvious differences between flooding group and control group 对香根草抗涝性指标的测定表明，淹水使香根草cat活性升高， sod活性基本不变， mda含量稍有积累，但质膜透性没有明显变化。

On the whole , vetiver showed much adaptation to flooding in morphology and physiology and had strong resistance to flooding . so vetiver is an amphibious plant and could be planted along river banks and reservoir banks where water levels fluctuate 总之，在淹水条件下香根草在形态和生理上都出现了适应性的变化，抗涝性极强，具有两栖特性，可考虑在水库库岸、河岸等水位易波动地区种植。
