锰超富集植物垂序商陆(Phytolacca americana L．)的认定

Identity of Phytolacca americana L.(Phytolaccaceae),Pokeweed:a manganese hyperaccumulator plant

针对目前国内锰超富集植物商陆属(Phytolacca)植物名称混乱的状态,在重新审查锰超富集植物——商陆(Phytolacca acinosa Roxb.)的野外标本和温室培养植物的基础上,比对中国科学院昆明植物所标本馆的腊叶标本,并查阅相关文献资料,以期正确认定锰超富集累植物的学名。结果表明,湘潭锰矿尾矿废弃地原生的锰超富集植物实为垂序商陆(Phytolacca americana L.),国内外相关研究论文中出现的商陆和美洲商陆实为垂序商陆的同物异名。这一植物名称的认定,将对避免锰超富集植物研究重复进行、保证相关研究正常有序开展具有重要意义。

Current confusion in the taxonomy of the genus Phytolacca and interest in the manganese hyperaccumulative trait reported in P. acinosa Roxb. has led to an extended field sampling, glasshouse cultivation and comparison with herbarium materials of P. americana L. s.l. Our specific aim was to identify and name the manganese hyperaccumulator plant correctly. The study indicated that the manganese hyperaccumulator plant P. acinosa which we first reported from the Xiangtan manganese tailings wasteland must be reduced to P. americana as a synonym. The identity of P. americana will administer to the academic development by avoiding the sameness of scientific research .
