| Abstract: | In order to study the relation of leaf color and chlorophyll content of Prunus virginiana,the chlorophyll content,carotenoid content in April,May,June,July,September,October and leaf color change rule in a year of Prunus virginiana were studied.The results showed that the chlorophyll a,chlorophyll b,chlorophyll a/b ratio,total chlorophyll content of Prunus virginiana in young leaf were smaller than those of old leaf.The carotenoid content of young leaf and old leaf were higher than mature leaf.The leaf color of Prunus virginiana was stable in a year.It was one of illumination landscape tree and also a kind of good local color plant in North of China. |
