| 摘 要： | 对干旱、半水淹和对照(正常灌水)等三种处理香根草在30d后的生长状况,以及退水、复水40d后三种处理香根草对光合有效辐射(PAR)增强的光合生理主要特征进行研究。结果表明:复水、退水后,干旱、半水淹处理香根草Pn、Tr和WUE均已恢复正常,说明香根草具有相当强的抗旱耐涝能力。

| Abstract: | This paper dealt with the growth of vetiver grass after the 30 days three treatments of drought,half-drown and normal,and the responds of photosynthesis under the condition of man-controlled different gradient photosynthetic active radiation(PAR)when three treatments relieved after 40 days. The result showed that photosynthetic rate(Pn),transpiration rate(Tr)and water use efficiency(WUE) come back normal when three treatments relieved after 40 days. Vetiver grass has more strongly ability of resisting drought and drowning. |
