滇西北玉龙雪山报春花种质资源的调查

滇西北玉龙雪山地处报春花属的现代形成与分布中心,有非常丰富的报春花种类。根据作者2003~2004年对玉龙雪山报春花属植物进行系统调查和资料整理,表明该地区有报春花40种(包括亚种与变种),占我国产报春花属植物总数的12%及云南产报春花属植物总数的29%;同时研究了该属植物在玉龙雪山的分布规律及其资源的生境类型并介绍了主要种类的生物学性状及观赏价值(包括花、叶及其开花期);而且对玉龙雪山报春花资源的保护及合理开发利用提出了建议。

Investigation on germplasm resources of the genus Primula L.in the Yulong Mountains, Northwest Yunnan

The region of Yulong Mountains,located in northwest of Yunnan Province,is one of the centers of modern distribution and formation for primroses (Primula)and is very rich in primroses. According to the investigations and data analysis in 2003～2004,totally 40 primroses taxa (including species,subspecies and varieties)were recorded in the region,which is 12% of the Primula in China and 29% of the Primula in Yunnan Province. Their distribution patterns and habitats in the research region were observed and described,and the biological characteristics and the ornamental features (e.g. flowers,leaves and blooming seasons)of some important taxa were provided in the present paper. Finally,suggestions to conserve and sustainably develop the primrose germplasm resources in the Yulong Mountains were also proposed in this paper.
