摘要
短序润楠(Machilus breviflora)是华南地区极具开发潜力的园林树种之一。文章在分析短序润楠生物学特性基础上,对3 a生短序润楠实生苗春梢嫩叶生长过程的色彩及SPAD值变化情况进行了观测研究。结果表明:短序润楠试验样株春梢的叶色在春季呈现不同的变异类型,可分为橙色、红色和紫色3个色系;嫩叶叶色变化过程中出现紫色系、褐色系、橙色系和绿色系;嫩叶生长过程中,SPAD值逐步增加。
Machilus breviflora is one of developing and potential landscape plants in south China. Based on the analysis of the biological characteristics of M. breviflora, the changes of soil and plant analyzer development（SPAD） value and the color of 3-year-old seedling M. breviflora in the young shoots growth were studied. The results showed that the leaf color of M. breviflora spring shoots showed different variation types in spring, which could be divided into orange, red and purple. The purple, brown, orange and green color appeared in the course of leaf color change, and the SPAD value increased gradually during the growth of young leaves.
