| 摘 要： | 在水淹和干旱条件下对加拿大一枝黄花的光合和荧光参数的影响进行了研究.结果表明:一定时间内,水淹促进了加拿大一枝黄花生长,而干旱胁迫可严重抑制植株的生长,表现为15 d的水分胁迫试验中,水淹植物的叶绿素含量、光下可变荧光与光下最大荧光的比值Fv'/Fm’、表观光合电子传递速率ETR、光化学淬灭系数qP和净光合速率NPR增加,最小荧光值Fo下降,可变荧光与最大荧光之比值Fv/Fm变化不大；而干旱胁迫植物的叶绿素含量、Fv'/Fm'、Fv/Fm、ETR、qP和NPR下降,Fo值上升,处理15 d后植株死亡. |

| Abstract: | The effect of flooding stress and drought stress on the photosynthesis and fluorescence of Solidago canadensis was studied.The results showed that during a certain period of time,flooding stress accelerated the growth of plants,however,drought stress greatly suppress the growth of plants.During the 15 days’ experiment,for flooding stress plants,the trends were embodied in the increasing value of chlorophyll,the ratio of lighting variable fluorescence to lighting maximum fluorescence(Fv’/Fm’),photosynthetic electron transport rate(ETR),photochemical quenching(qP)and net photosynthetic rate(NPR),the decreasing value of the minimum fluorescence(Fo),while the change of the ratio of variable fluorescence to maximum fluorescence(Fv/Fm)was not obvious;for drought stress plants,the trends embodied in the decreasing value of Chlorophyll,Fv/Fm,Fv’/Fm’,ETR,qP and NPR,the increasing value of Fo,the plants were dead after treating 15 days. |
