摘　　要：[目的]为大叶黄杨与金边黄杨的培育与研究提供参考。[方法]以浙江省慈溪市内的卫矛属大叶黄杨及其变种金边黄杨为研究对象,分析了叶片长度和宽度、面积和生物量的生长规律,比较2种植物叶片在生长上的差异。[结果]2种植物的叶片有着相似的数量特征,大叶黄杨叶片长度为39.5±8.6cm,宽度为22.2±5.8cm,叶面积为635.1±274.6cm2,叶生物量为0.046±0.024g;金边黄杨叶片长度为37.2±8.6cm,宽度为18.8±4.4cm,叶面积为499.8±207.8cm2,叶生物量为0.03±0.016g。大叶黄杨叶片的宽度与长度呈极显著直线函数关系,金边黄杨叶片则为极显著对数函数关系;二者的叶生物量与叶面积均呈极显著的幂函数关系,呈现异速生长规律。[结论]大叶黄杨和金边黄杨成株叶片在叶长、叶宽、叶面积及叶生物量等数量性状均具有较大的表型可塑性。[Objective] The research aimed to provide reference for the breeding and research of Euonymus japonwus and Euonymus 3apontcus cv. Aureo-ma. [ Method] Taking Euonymusjaponicus and its variation Euonymusjaponicus ev. Aureo-ma in Cixi City of Zhejiang Province as research objects, the growth laws of leaf length and breath, area and biomass were analyzed and the growth difference of the leaves between the two plant species were compared. [ Resuh] There was a similar quantitative characteristics of the two plants. The leaf length of Euonymus ja- ponicus was 39.5±8.6 cm and the width was 22.2±5.8 cm, the leaf area was 635.1±274.6 cm^2 and biomass of leaf was 0. 046±0. 024 g. The leaf length was 37.2±8.6 cm and the width was 18.8±4.4 cm, the leaf area was 499.8±207.8 cm^2 and the biomass of leaf was 0.03±0.016 g. The relationship of the leaf length and width was described best by linear function for Euonymus japonicus and Euonymus japonicus cv. Aureo-ma showed a logarithmic function. The relationships of its leaf area and biomass of leaf in the two plants were described best by power function, showing the regulation of isogony. [ Conclusion] There is a large number of phenotypic plasticity in the leaf length, breadth, area and biomass of the two plants.
