云南竹亚科珍稀种质资源及其开花结实研究

Study on Rare Germplasm Resources in Bamboo Subfamily and Its Flowering Fruitification in Yunnan,China

论述了云南竹亚科种质资源的基本特点,并对云南珍稀特有种质资源进行了较详细的分析,按属、种排序提出了不同保护等级的保护竹种名录。竹子开花周期较长,许多竹子结实率低,种子的收集、保存和繁殖较为困难,探讨了一些重要竹类开花、结实及采集、保存和利用问题。

Yunnan is very rich in bamboo resources which are in wide range and there are many valuable and rare bamboo species. This paper discusses the basic characteristics of valuable and rare germplasm resources in bamboo subfamily, and analyzes in detail the germplasm resources endemic to Yunnan and presents bamboo species list that should be classified as the list of wild plants of national priority protection according to genera and species. Since bamboo experiences long flowering period and many bamboos have very low seed setting rate, the collection, preservation and propagation of seeds are rather difficult. The paper also discusses these issues, probing into the flowering, seed setting, and seed gathering, preservation and utilization of some important bamboos.
