【摘要】 通过查阅文献结合7年实地考察,对中国西南地区(四川、云南、西藏)野生牡丹资源的种类、分布和生物学特性进行了系统调查,对部分野生种通过播种繁殖进行了引种驯化。结果表明:中国西南地区共有野生牡丹5种,1个亚种,且均为西南地区特有。对四川牡丹(Paeonia decomposita)及西藏黄牡丹(P.lutea)、大花黄牡丹(P.ludlowii)资源分布情况及特点进行了报道。引种驯化表明,西南所有野生种均能在西藏拉萨引种驯化成活:四川牡丹耐高温、干旱,忌水湿;狭叶牡丹适应性最强,在多地引种成活;黄牡丹和大花黄牡丹能在西藏拉萨、甘肃兰州和河南洛阳海拔1700m以上地区引种成活。结合实地调查,分析了西南野生牡丹濒危原因,并对其保护与开放利用提出建议。更多还原

【Abstract】 Referring to literature and on-site study,we investigated the resource distribution and biological of wild peony in southwest China,introduce some species by spreading seeds.Results indicate that there are 5 wild species and 1 subspecies,accounts for more than half of China’s wild peony,and are unique in southwest China.In this paper,the resource distribution and the characteristic of Paeonia decomposita,P.lutea and P.ludlowii are reviewed.According to experiments on introduction and cultivation,all the wild species in southwest China can survived in Lhasa,Paeonia decomposita adaptives to high temperature and drought,does not bear wet Paeonia delavayi Franch.var.angustiloba Rehder & E.H.Wilson is the most well adjusted.We also give an analysisi on the reasons of wild peony being endangered,and especially give a discussion on protection and utilization.更多还原
