中文摘要：
采用盆栽方式模拟田间试验,研究了水分胁迫对皇竹草形态和叶片光合特性的影响.结果表明,在短期（6 d）淹水条件下皇竹草形态没有明显变化,而长期（21 d）淹水导致皇竹草茎长出大量须根、叶片出现失绿;淹水条件下皇竹草叶片的净光合速率、气孔导度、蒸腾速率均低于对照,叶绿素荧光Fv/Fm、Fo、Fm下降明显,叶绿素含量减少;干旱条件下,皇竹草叶片逐渐出现枯黄,且随着干旱程度的加深,叶绿素荧光Fv/Fm、Fo、Fm降低,叶绿素含量减少.
英文摘要：
A pot experiment was conducted to clarify the effects of water stress on morphological and photosynthetic characteristics of hybrid giant napier （Pennisetum hydridum）. The results showed as follows： there were no obviously changes of Hybrid giant napier under the short-term flooding （6 d）, however stems grew a large number of fibrous roots and leaves lost green under long-term flooded （21d）. The photosynthetic performance, chlorophyll fluorescence Fv/Fm, Fo, Fm and chlorophyll content decreased significantly in the leave of Hybrid giant napier under flooding. Leaves became yellow under drought condition. Chlorophyll fluorescence Fv/Fm, Fo, Fm and chlorophyll content decreased with the drought degree deepen.
