摘要:

为弄清不同变异类型杜仲果实含胶特性的变异规律,为杜仲胶优良资源的选择和有效利用提供理论依据,采用典型样株和随机取样的方法;含胶率的测定利用杜仲胶综合提取法。结果表明:4个变异类型的果实形态大小存在极显著差异。不同变异类型在果实形态大小上的不同,表明不同类型生长发育特性的差异;不同变异类型果实含胶率和果皮含胶率均存在极显著差异。果实含胶率和果皮含胶率以浅纵裂型最高,深纵裂型最低。

Abstract:

This study was conducted for fully understanding of gutta-percha content characters in samaras from different variance-types, which as a result provided theoretical guidance for selections of valuable resources and effective utilization of Eucommia ulmoides. Typical sample-tree selection and random selection were applied and integrated extraction was used for the gutta-percha content rate test in this study. The result showed that there existed remarkable differences of samara's shape and size among four main variance-types. These differences of samara's configuration and size indicated the growth characters among variances. Furthermore, significant differences of gutta-percha content rate in both kernel and pericarp were observed among variance-types. The highest gum content in kernel and pericap was obtained from while forma crackle lowest from forma split.
