关键词：
杜仲叶;次生代谢物;生长发育特性
摘  要：
通过同一立地条件下生长的 4 0个杜仲无性系叶中次生代谢物 (有效成分 )含量的测定 ,对杜仲个体生长发育特性与其次生代谢物含量的关系进行了分析 ,研究结果表明 :4 0个杜仲无性系叶中次生代谢物含量差异显著 ,从而进一步证明了杜仲个体生长发育特性 (遗传因素 )是调控次生代谢产物合成和积累的重要因素 ;芽开绽期早的个体 ,其次生代谢物含量高于芽开绽期晚的个体 ;椭圆形叶的杜仲胶含量明显高于卵形叶的个体 ;叶面积与杜仲胶含量呈显著的负相关 ;光皮类型的京尼平甙酸、京尼平甙含量高于粗皮类型 ;树木的性别、胸径生长量、树高生长量和硝酸还原酶活力则对次生代谢物含量无影响。这些研究结果为杜仲的良种选育提供了表型参考依据

摘  要：
Through determining the contents of secondary metabolites in Eucommia ulmoides Oliv. (Duzhong) leaves of different clones growing in the same site type, the result showed that the relationship between the growth features of individuals of Duzhong and the contents of secondary metabolites, and variance analysis of the contents of secondary metabolites is notable in different clones. The results show that the growth features of Duzhong (genetic factors) are important factors in regulating sythesis and accumulation of the secondary metabolites.\;Through analizing the relationship between the growth features of individuals and the contents of secondary metabolites, it is concluded that the contents of secondary metabolites in early budding individvals are higher than those in late ones, the gutta\|percha contents in individuals with oval leaves are appareatly higher than those in ones with elliptic leaves, leaf area is negatively relevant to the gutta\|percha content, the contents of geniposidio acid and geniposide in the smooth\|bark type are higher than those in the rough\|bark one; while sex, DBH, height and activity of nitrate reductase (NR) have no effects on the contents of secondary metabolites. These results provided theoretic basis for the selection of excellent clones.
