贵州树形杜鹃亚组及两个杂交种的种子形态研究

Research on Morphologic Characteristics of Seeds of Subsect.Arborea Sleumer and Two Hybrid Species of Rhododendron in Guizhou

本文利用扫描电子显微镜对贵州分布的树形杜鹃亚组的3个种及两个天然杂交种杜鹃种子形态进行了观察和对比研究。对杜鹃种子的四个主要形态指标进行描述,即种子的形状、大小、翅和肋,为其种间鉴别提供一定的科学依据。

Using scanning electron microscope, this paper describes four main morphologic characteristics of seeds of Subseet. Arborea Sleumer and two hybrid species of Rhododendron in Guizhou, including shape, size, wing and rib. It will provide a certain scientific basis for interspecies appraisal of Rhododendron.
