神农架野生紫斑牡丹引种调查研究

STUDIES ON THE INVESTIGATION AND INTRODUCTION OF THE WILD FLOWER PAEONIA SUFFRUTICOSA ANDR.VAR.PAPAVERACEA (ANDR.) KERNER IN SHENNONGJIA

本文报道了在湖北西部神农架地区发现的国家三级珍稀保护野生花卉紫斑牡丹(P.suffruticosa var,Papaveracea(Andr)Kerner.),及其自然杂交后代粉红花紫斑牡丹。调查研究表明,紫斑牡丹原产我国西北地区,后逐渐沿秦岭、大巴山系向东延伸,因地区环境不同,生长适应性亦有所不同。文中较详尽地讨论了紫斑牡丹的不同形态特征、地理分布、立地条件等,为进一步开展引种驯化、杂交育种工作提供了理论依据。

A few years ago, a rare and endangerous wild flower Paeonia suffruticosa Andr. var. papaveracea ( Andr. ) Kerner(f.albus)and its natural hybrid(f.rosea-pietus) were found by expedition to Shennongjia in the west region of Hubei ProvinceThis paper represents the different morphological characteristics, geographic distribution, ecological habit, site condition of the wild flower. According to our investigation, this species is originally distributed in the northwest of China, then gradually from Tsinlin and Daba mountain expand to Shennongjia area, between 1100—2500m region above sea level. Because the ecotopie and ecoclmatic are quite defferent, the growth adaptability is not similar too. This species may provide a very important germplasm for cross breeding.
