摘要
通过实地调查、标本查阅和文献检索 ,系统描述了我国芍药属牡丹组革质花盘亚组各种不同居群、种间杂种及‘凤丹白’实生苗的形态特征和变异 ,在此基础上提出了该亚组野生牡丹的分类性状 ,讨论了瓣基紫斑和花盘、花丝颜色的遗传规律及延安牡丹、林氏牡丹的分类地位 ,并认为栽培牡丹丰富的变异来源于反复的种间杂交。对革质花盘亚组形态演化趋势进行了初步探讨。
By investigating and specimen consulting and literatures searching,morphological characters and variations of different populations of every species,interspecies hybrids and a original cultivated type seedling'Fengdanbai'in Sect.Moutan Subsect Vagiatae were systematically observed and described.According to the results, the authors put forward some classificatory characters,genetic rules of purple blotches at the base of petals and color of flower disc and filaments,and drew a conclusion that plentiful variations of cultivated tree-peony coming from hybridization of wild species.Classificatory degree of Paeonia yananensis and P.rockii sp.linyanshanii were also discussed.Finally,morphological evolvement trends in the subsect were elementarily analysed.
