摘要
用分光光度法对10种彩叶树生长季和非生长季的叶片叶绿素a、叶绿素b和类胡萝卜素含量进行测定。结果表明,红叶李、碧桃和海棠叶绿素含量较高,红叶李、银杏和碧桃类胡萝卜素含量较高。多数彩叶树种在生长季叶绿素含量显著高于非生长季;不同彩叶树种类胡萝卜素含量在生长季和非生长季无明显差异。
The contents of carotenoi and chlorophyll a,chlorophyll b in the leaves of 10 kinds of colored leaf trees in growing season and non-growing season were determined by spectrophotometry.Result shows that the chlorophyll content of Prunus cerasifera,Amygdalus persica & Malus spectabilis is higher;carotenoid content of Prunus cerasifera,Ginkgo biloba & Amygdalus persicais higher.The chlorophyll content of most color-leaved tree species in the growing season was significantly higher than that in the non-growth season.The carotenoid content of different color-leaved tree species has no significant difference between the growing season and the non-growth season.
