【 摘 要 】

ThepsbA-trnH intergenic region was studied for authenticatingCurcumalongaand its two related species (CurcumasichuanensisandCurcuma chuanhuangjiang). The sequences were analyzed by means of Neighbor-Joining to improve the phylogenetic resolution of these threeCurcumaspecies. The genetic diversity of these three species is 0.009 to 0.014 (< 0.05).The results show that partial population specimens ofC. sichuanensisoriginate from the cultivated mutation ofC. longa; and retain theC.chuanhuangjiangas an individual species.The differentiation is engendered between the wildness and cultivated specimens withinC. longaspecies.
