Abstract:

For the development of medicinal Dendrobium industrialization, the study aims to reduce the dependence on wild traditional Chinese medicine resources and select excellent germplasm resources suitable for artificial cultivation, thus realizing the coordination between the sustainable development of traditional Chinese medicine industry and ecological environment protection. 13 primary germplasm resources of Dendrobium officinale introduced and collected in Yingshan of Hubei Province were used as test materials, and the phenology observation, stem and leaf morphology and flower morphology observation were conducted, and the growth adaptability of different germplasm resources was compared. The results show that the phenological periods of different medicinal Dendrobium germplasm resources are different. The earliest flowering period is at the end of March, most of them are from April to May, and the latest is from July to August. There are significant differences in stem, leaf and flower morphology among different germplasm resources, which could be divided into three types: high, common and small. The color of petals and lips of different medicinal Dendrobium germplasm resources mainly change from white to yellow green. The petals are mainly leathery, and a few of them are thick leathery, paper like or membranous. Dendrobium huoshanense, Dendrobium officinale, Dendrobium moniliforme and Dendrobium lohohense have better growth adaptability. Yingshan County of Hubei Province has superior geographical and climatic conditions, which are suitable for the growth of most medicinal Dendrobium. Phenological period, stem and leaf morphology and flower morphology are important indexes to distinguish the germplasm types of medicinal Dendrobium. Dendrobium huoshanense, Dendrobium officinale and Dendrobium moniliforme (Jiangxi provenance) are high-quality germplasm resources that can be popularized and developed in Hubei Province.

Key words: medicinal Dendrobium, germplasm resources, phenophase, morphological observation, adaptability
