DENG, JB et al. Relationships among six herbal species (Curcuma) assessed by four isozymes. Phyton (B. Aires) [online]. 2011, vol.80, n.2, pp.181-188. ISSN 1851-5657.

Four isozymes, superoxide dismutase (SOD), polyphenol oxidase (PPO), malate dehydrogenase (MDH) and cytochrome oxidase (COD) were studied for identification of six herbal species (Curcuma L.). All the 37 study specimens produced a total of 168 polymorphism isozyme bands. The genetic distance coefficients (GS) varied from 0.08 to 0.54. The dendrogram, obtained according to the polymorphism isozyme bands by the UPGMA method with the software NTSYS-pc2.1, contributed to improve the resolution of phylogeny. From the dendrogram, it was possible to differentiate between the wild and cultivated specimens of C. longa, and within C. sichuanensis species.
