浙西北15个树种叶片叶绿素含量分析

摘要

以浙江西北地区的15个常见树种为研究材料，测定了幼苗叶片叶绿素含量，对叶绿素(a+b)含量及叶绿素a/b进行聚类分析，结果表明：马尾松和苦槠的叶绿素(a+b)含量较低，而叶绿素a/b较高；美丽胡枝子的叶绿素(a+b)含量及叶绿素 a/b 均较高；杜英、浙江楠、竹柏、水杉、石栎、木荷、短尾柯、红花檵木、乌桕、红豆杉、乌冈栎、红叶石楠的叶绿素(a+b)含量及叶绿素a/b居于中间水平。%15 common tree species in the northwestern part of Zhejiang province were selected for determination of chlorophyll content. Cluster analysis on their chlorophyll (a+b) content and chlorophyll a/b showed that chlorophyll (a+b) content inPinus massoniana andCastanopsis sclerophyllawas lower but their chlorophyll a/b was highe. Chlorophyll (a+b) content and chlorophyll a/b inLespedeza formosa was higher, and that inElaeocarpus decipiens, Phoebe chekiangensis,Podocarpus nagi,Metasequoia glyptostroboides,Lithocarpus glaber,Schima superba,Lithocarpus brevicaudatus,Loropetalum chinense var.rubrum,Sapium sebiferum,Taxus chinensis,Quercus phillyraeoides,Photinia fraseri wae in the middle level.
