摘要
以长春市园林绿化树种中常见的榆叶梅、锦带、连翘、紫丁香为研究对象,采用自然条件定位观测的手段,全面系统地比较了4种园林绿化植物叶片的叶绿素a、b含量、叶绿素(a+b)含量、叶绿素a/b值、叶绿素b/(a+b)值、光饱和点,光补偿点、最大净光合速率等8项生理指标的特征,研究其耐阴性。结果表明:榆叶梅、紫丁香的耐阴性较弱;连翘有一定程度的耐阴性;锦带的耐阴性较强。
Common varieties of trees of Prunus triloba Lindl.,Weigela florida,Forsythia suspensa（Thunb.） Vahl.,Syringa oblata Lindl.were used as research object in Changchun city,located observation by means of natural conditions.,and take a comprehensive and systematic comparison with the four types of landscape plants＇ chlorophyll a,chlorophyll b,chlorophyll（a＋b）,the values of chlorophyll a/b,the values of chlorophyll b/（a＋b）,light saturation point and light compensation point,maximum net photosynthetic rate and so 8 physiological indicator,studied their shade tolerance.The results showed that Prunus triloba Lindl.and Syringa oblata Lindl.＇s negative resistance was weak;Forsythia suspensa（Thunb.） Vahl.had a certain degree of shade tolerance;Weigela florida ＇s Negative resistance was strong.
