Effects of water stress on photosynthetic pigment in leaves and chlorophyll fluorescence of Cynanchum komarovii

HE Jun~1,XV Xing~1,LI Shu-hua~1,MI Hai-li~1,ZHANG Yuan-pei~2, ZHAO Tian-cheng~2,MA You-ming~3 ina;2 Soil and Fertilizer Research Laboratory,Ningxia Academy of Agricultural and Forestry Sciences,Yinchuan 750002,China;3 Ningxia University,Yinchuan 750021,China)  
Effects of water stress on photosynthetic pigment and chlorophyll fluorescence induction kinetic parameter in leaves of Cynanchum komarovii were studied.The results showed the content of chlorophyll a (Chl a),b (Chl b) and carotenoid (Car) in leaves of Cynanchum komarovii did not decrease or decreased little in the course of water stress.But it decreased significantly after a long time of water stress.The chlorophyll fluorescence induction kinetic parameters Fo,Fm,Fv,Fv/Fm changed little.In last stage of all treatments,Fo decreased,but Fm,Fv,Fv/Fm increased under lightly and serious water stress.Which showed the photosynthesis of Cynanchum komarovii would be influenced after a long time of water stress.But Cynanchum komarovii still showed high adaptability to water stress.
