对不同生境夏蜡梅营养器官的总黄酮和总绿原酸含量进行测定,并分析了与环境因子之间的相关性.结果表明:(1)夏蜡梅不同营养器官的总黄酮含量叶片最高,其它器官的含量很低;总缘原酸含量叶、根中的含量较高,其它器官也有一定的含量.3个不同海拔高度夏蜡梅叶片的总黄酮与总绿原酸含量呈极显著的正相关.(2)夏蜡梅7个居群叶片总黄酮含量在3.4979%~5.1779%,其中大雷山2个居群的含量高于临安居群,差异极显著;7个居群叶片总绿原酸含量变化范围为2.6991%~4.5873%,大雷山2个居群的含量也高于临安居群 ...

对天台大雷山4个不同生境(常绿阔叶林、灌丛、竹林和杉木林)夏蜡梅群体的果实、种子形态变异及其与环境因子的相关性进行了研究.测量的果实和种子12项形态学指标表明,果实和种子的性状以灌丛生境最优、其次是竹林生境、最差的是常绿阔叶林生境.表型性状在群体间和群体内都存在着一定程度的变异,其中群体间的变异系数的平均值从61.71(每果种子数)到7.51(种子厚).夏蜡梅种子形态较果实形态穗定.单因素方差分析显示,夏蜡梅果实和种子形态在不同生境间差异显著,其中80%以上的变异来源于生境内 ...

Photosynthesis traits of the endangered plant species Sinocal ycanthus chinensis(濒危植物夏蜡梅光合生理生态特性)
采用遮荫的方式设置3个光照梯度:全光照(CK)、37%全光照(37%RI)和10%全光照(10%RI),于2007年7月中旬,对上述光环境中的夏蜡梅(Sinocalycanthus chinensis)幼苗的光合作用参数、叶绿素荧光参数进行测定,结果表明:3种光环境下,夏蜡梅的净光合速率日变化均为“双峰”曲线,CK和37%RI光环境下,午休现象明显;最大净光合速率的大小是37%RI>CK>10%RI;日均净光合速率的大小是37%RI>10%RI>CK.叶绿素荧光参数的日变化表明,10 ...
