By using spectrophotometry method determinated the anthocyanindin and chlorophyll content in different parts of Prunus wilsonii leaves,results showed that,as time changes,anthocyanins content in different parts of the leaves showed a low-high-low change in trend,the analysis of variance,the difference is not significant,relations between anthocyanidin content in Prunus wilsonii leaves and the position of health was not obvious,anthocyanindin content in the same part are far greater than chlorophyll content,...

用分光光度法对紫叶稠李叶片不同部位的花青素和叶绿素进行了测定，结果表明，随着时间的变化，不同部位叶片的花青素均呈现低-高-低的变化趋势，经方差分析，差异性不显著，说明紫叶稠李叶片花青素含量跟着生的部位关系不明显；同一部位的花青素含量远远大于叶绿素含量，这也是紫叶稠李叶片在整个生长季呈现紫红色的原因。
