摘要
Nineteen Cymbopogon taxa belonging to 11 species, two varieties, one hybrid taxon and four unidentified species were analysed for their essential oil constituents and RAPD profiles to determine the extent of genetic similarity and thereby the phylogenctic relationships among them. Remarkable variation was observed in the essential oil yield ranging from 0.3% in Cymbopogon travancorensis Bor. to 1.2% in Cymbopogon martinii (Roxb.) Wats var. motia. Citral, a major essential oil constituent, was employed as the base marker for chemotypic clustering. Based on genetic analysis, elevation of Cymbopogon flexuosus var. microstachys (Hook. F.) Soenarko to species status and separate species status for C. travancorensis Bor., which has been merged under C.flexuosus (Steud.) Wats were suggested towards resolving some of the taxonomic complexes in Cymbopogon. The separate species status for the earlier proposed varieties of C. martinii (motia and sofia) is further substantiated by these analyses. The unidentified species of Cymbopogon have been observed as intermediate forms in the development of new taxa. (C) 2004 Elsevier Ltd. All rights reserved.
