茶树原产我国。由于栽培历史悠久,地域广阔,以及茶树生长在不同的生态环境和经过长期的人工选育,使得我国具有十分丰富的品种资源。本文选取云南、四川、贵州、广东、福建、浙江的20份资源用光学显微镜和扫描电镜观察其花粉形态.以为合理利用茶树资源和资源分类提供资料和依据。 Tea tree origin China. Due to its long history of cultivation, vast territory, and the growth of tea trees in different ecological environments and long-term artificial breeding, our country has a very rich variety of resources. In this paper, pollen morphology of 20 resources in Yunnan, Sichuan, Guizhou, Guangdong, Fujian and Zhejiang Provinces were observed by light microscopy and scanning electron microscopy, which provided information and basis for rational utilization of tea tree resources and resource classification.
