| ABSTRACT To study the development rules of Chinese native geese, two breeds, Shitou and Sichuan White geese were analyzed from 0 to 12 weeks of age. The growth curves were fitted with commonly used four kinds of nonlinear models (Logistic, Gompertz, Von Bertalanffy and Richards). The results showed that the growth curves were appropriately fitted with all four models but the Logistic and Richards both had the best fitting with growth curve (R2>0.99). Analyzing the fitting parameters of the Logistic and Richards, we found that male Shitou had the highest adult body weight while Sichuan White female had the lowest weight. In Shitou breed, Shape parameter Predicted with Richards model was corresponded with Gompertz curve, while in Sichuan breed it was in... |

| 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. |
