Objective Wild resources,ecological environment,growth and development regularity of wild Gentiana straminea Maxim.in Qinghai were investigated to provide theoretical basis for domestication and cultivation of G.straminea.Methods Germplasm resources of wild G.straminea in Qinghai were investigated and analysed via going through all related references and field investigations.Results G.straminea is spread in Qinghai province and optimally growing in river bank,forest edge,shrub and grassland with moist,sub-shading and warm environment.Environmental factors affecting quality of G.straminea herbs are mainly soil and water,Environmental factors affecting the population density of G.straminea are mainly the height and density of communities associated plant.Conclusion Wild G.straminea is wide spread in Qinghai province,reproduction and regeneration of G.straminea are dramatically affected by special growth conditions and relatively long growth period,and human factors result in the destruction of resources.
