【目的】结合枸杞栽培品种之间光合参数和叶绿素荧光参数的差异性分析，对比研究了9个枸杞栽培品种间光合气体交换参数和内在品质差异。【方法】在田间试验条件下，试验采用随机区组设计，分别于7、8月晴天上午9：30-11：30之间测定光合及荧光指标，研究分析各供试品种间枸杞的内在品质，并分析其差异。【结果】以宁杞3号Pn、WUE、WUEi、PSⅡ最大光化学效率（Fv/Fm ）和PSⅡ潜在活性（Fv/Fo ）都显著高于其他8个供试品种，揭示了宁杞3号的光合能力和水分利用效率最强；并且进一步得出宁杞3号的多糖、总糖、黄酮、甜菜碱、类胡萝卜素含量都居于首位，其中甜菜碱的含量显著高于其他供试品种。其次为扁果枸杞、宁杞1号、宁杞4号、7号，再次为宁杞5号、0901、蒙杞1号，0702的光能利用率和果实品质较弱。【结论】结合各品种的光合气体交换参数及叶绿素荧光参数，进行不同枸杞栽培品种间的品质对比分析，得出宁杞3号、宁杞1号、宁杞4号、宁杞7号、扁果枸杞，这5个栽培品种非常适宜大面积推广种植；宁杞5号、0901可以作为辅助品种适当发展；而蒙杞1号、0702这2个品种不适宜发展种植。

Objective The aim of this experiment was to compare chlorophy Ⅱfluorescence,pho-tosynthetic parameters and fruit quality among 9 L?barbarum cultivars?[Method]This experi-ment was a completely randomized design the chlorophyll fluorescence and photosynthetic parame-ters of each cultivar were measured in the field conditions between 9:00 to11:30 in July and Au-gust?Moreover,the fruit quality was also analyzed?[Results]Ningqi-3 showed higher Pn , WUE,WUEi ,PSⅡ(Fv/Fm )and PSⅡ(Fv/Fo )compared to other 8 cultivars,suggesting that Ningqi-3 has higher photosynthetic capacity and stronger water utilization ability and light ener-gy?Ningqi-3 exhibited the highest values in total sugar,polysaccharide content,sweet fruit base, flavonoid and carotenoids?The light use efficiency and fruit quality were lower in 0702 than in other cultivars?[Conclusion]According to chlorophyll fluorescence,photosynthetic parameters and fruit quality,Ningqi-3 ,Ningqi-1 ,Ningqi-4 ,Ningqi-7 and Bianguogouqi may be popularized in this area?Ningqi-5 and 0901 could be an assistant cuitivar?Mengqi-1 and 0702 is not suitable for development in this area.
