山葡萄"左优红"与"北冰红"叶绿素荧光参数的日变化比较研究

[目的]探讨同一栽培地区2个山葡萄品种的荧光差异,为山葡萄高效栽培及优良品种选择提供技术支持。[方法]用植物效率分析仪（Pocket PEA）测定了山葡萄＂左优红＂与＂北冰红＂的叶绿素荧光参数,采用Excel、SAS等软件进行数据分析。[结果]在一天中,＂左优红＂和＂北冰红＂Fo均在中午出现最低值,说明＂左优红＂和＂北冰红＂可通过增强非辐射能量耗散来消耗过剩的光能,从而避免光合器官遭受破坏;＂左优红＂Fv/Fm高于＂北冰红＂3.9%,差异显著,表明＂北冰红＂对光抑制比＂左优红＂敏感;＂左优红＂的PI值比＂北冰红＂高30.4%,差异显著,表明＂左优红＂比＂北冰红＂具有更高的光能转化效率。[结论]山葡萄＂左优红＂的抗逆性高于＂北冰红＂。

Comparative Research on Diurnal Changes of the Chlorophyll Fluorescence Parameters of Vitis amurensis Rupr. "Zuoyouhong" and "Beibinghong"

[Objective] The aim was to discuss the difference of chlorophyll fluorescence between Vitis amurensis Rupr.Zuoyouhong and Beibinghong,so as to provide the theoretic reference for the introduction and cultivation production of plants.[Method] The diurnal variations of their chlorophyll fluorescence parameters were determined by Pocket PEA,Excel and SAS were adopted to analyze the date.[Result] The lowest Fo value of both Zuoyouhong and Beibinghong occurred at noon.And the parameters of Fo display that in ord...
