Objective:
To compare difference in character between wild germplasm and cultivar of Rehmannia glutinosa Libosch.
Method:
Field test and statistical analysis were applied.
Result:
The results showed that the plant height and leave weight of individual plant in cultivar were decreased significantly comparing to wild germplasm, and the output was increased significantly. The leave length was reduced. The leave width, the catalpol content in leave and polysaccharides and reducing sugar content in cultivar was increased not significantly. Whereas the catalpol content and the water extract content in cultivar were equal to wild germplasm.
Conclusion:
The plant height and leave weight of individual plant of R. glutinosa was decreased significantly in cultivar, but the active compounds content not changed obviously.
