峨眉山野生报春花种质资源的调查

Investigation on Germplasm Resources of Wild Genus Primulain Emei Mountain

为峨眉山报春花资源利用与保护提供依据,同时为促进峨眉山的生态旅游提供参考,采用系统调查与资料整理相结合的方法对峨眉山野生报春花种质资源及主要种类的生物学观赏特性进行研究。结果表明：峨眉山共有野生报春花13种（包括亚种及变种）,其中,晚花卵叶报春（Primula tardiflora）和峨眉缺裂报春（P.homogama）为特有种;该属植物在峨眉山分布于海拔600~2 500m,该资源的分布东坡优于西坡;主要生境类型为岩生型和林缘、林内阴湿型。对峨眉山野生报春等几个主要种类的生物学特性（花、叶以及开花期）进行描述,并对峨眉山野生报春花种质资源的保护和合理利用提出了建议。

To preferably use and protect germplasm resources of wild genus Primula in Emei Mountain,and to provide references for promoting ecological tourism of Emei Mountain,methods of field survey and data analysis were employed to investigate the wild Primula germplasm resources and ornamental characteristics of major species in Emei Mountain.Results：Totally 13 primrose species（including species and subspecies）were recorded in the region,among them,P.tardiflora and P.homogama were endemic to Emei Mountain;The genus mainly distributed in the elevation of 600~2 500 min Emei Mountain,and the resources in eastern slope were more than that in western slope,and the main habitat types were rock type,type of forests and forest damp.The ornamental features of P.tardifloraand P.homogamaincluding flowers,leaves and blooming seasons of some important taxa were described.Suggestions to conserve and sustainably develop the primrose germplasm resources in Emei Mountain were also proposed in this paper.
