摘要 [目的]了解黄花柳资源的变异特性。[方法]以黄花柳3个无性系为材料,通过柯尼卡CR-400全自动色差计对其叶色参数进行测定,通过乙醇提取方法对其叶绿素含量进行测定,使用Pocket PEA快速荧光仪对其叶绿素荧光特性进行分析比较。[结果]叶绿素含量与L、a均呈显著负相关;金枝黄花柳的叶色偏黄、叶绿素含量较低,但其潜在光化学活性最强,对强光胁迫具有较强的自我保护能力;普通黄花柳叶色偏绿、叶绿素含量较高,其潜在光化学活性也较强,但其对光能的利用率最低;红枝黄花柳的叶色较金枝黄花柳偏绿,较普通黄花柳偏黄,其叶绿素含量与光能利用率均介于二者之间。[结论]叶绿素含量越高叶片颜色越偏绿色且越明亮;金枝黄柳较其他2个黄花柳无性系叶片颜色更鲜艳,且其光化学活性最强,对光能的利用率最大。 [Objective]To know about the variation characteristics of the resources of Salix caprea .[Method]We used three clones of S. caprea as experimental materials,determined its leaf color parameters by Konica CR-400 and its chlorophyll content by ethanol extraction method. The fluorescence characteristics of the chlorophyll were analyzed and compared using the Pocket PEA fast fluorometer.[Result]The chlorophyll content was negatively correlated with L -value and a -value. S. caprea ‘GoldenStem’ had yellow color leaves and lower chlorophyll content, but its photochemical activity was the strongest, so it had strong self-protection ability against strong light stress.For common S.aprea ,it’s leaf color was greenish, the chlorophyll content was higher, and its potential photochemical activity was stronger.The color of S. caprea ‘RedenStem’ was greenish compared with the S.aprea ‘GoldenStem’, the chlorophyll content and utilization of light energy were between the two clones.[Conclusion]The higher the chlorophyll content, the more green and bright the leaves are. The color of S.aprea ‘GoldenStem’ is more vivid than the other two clones, and S.aprea ‘GoldenStem’ had strongest photochemical activity and maximum utilization of light energy.
