摘要
【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.
