英语翻译用分光光度法对不同时期紫叶李和普通绿叶李叶片中叶绿素、类胡萝卜素和花青素的含量进行测定分析,系统观察和记载两种树木的叶色变化.结果表明:在3月到7月,紫叶李叶片中叶绿素、类胡萝卜素和花青素含量总体上均呈上升的趋势,叶绿素a和b含量的变化趋势与叶绿素总量的变化趋势相似,三种色素的综合作用使紫叶李叶色越来越深;紫叶李叶色与三种色素的变化呈正相关关系;绿叶李叶色与叶绿素/类胡萝卜素呈正相关关系,对绿叶李的叶色变化起主要作用的是叶绿素和类胡萝卜素,绿叶李叶片中花青素含量的变化不显著,它对叶色变化的影响有限

To test and analyze the chlorophyll,carotinoid and anthocyanin contents of leaves from prunus cerasifera (或purple - leafed plum)in different periods and ordinary green-leafed plum with spectrophotometry,and then to observe and record systematacially the changes of leaf colour of these two plants,here comes the results:from March to July,the chlorophyll,carotinoid and anthocyanin contents of leaves from prunus cerasifera overall increased,the changing tendency of chlorophyll a and b total contents are similar to the chlorophyll total content.The leaf colour of purple - leafed plum became darker and darker,which is due to the comprehensive effect of these three pigments.The leaf colour of purple - leafed plum has direct correlativity with the contents of the three pigments.There is also a positive correlation between green- leafed plum and chlorophyll/carotinoid.Chlorophyll and carotinoid play the most important role in changing leaf colour of green- leafed plum whose the anthocyanin content ,which gets limited influence on changing leaf colour,is no significant change.
