摘　　要：目的:比较地黄栽培品种与野生品种的性状差异,为地黄新品种的选育提供理论依据。方法:利用田间试验结合统计分析。结果:与野生品种相比,栽培品种株高明显降低、单株叶片数明显减少、产量显著增加;与野生品种比较,栽培品种叶片长度有所减少,叶片宽度、叶片中梓醇含量、多糖和还原糖有所增加但不明显,而块根中梓醇含量和水浸出物含量基本相同。结论:人工选育使地黄的株高降低、叶片数减少,产量增加,但有效成分含量没有明显改变。Objective： To compare difference in character between wild germplasm and cuhivar 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 po]ysaecharides 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.
