To compare difference in character between wild germplasm and cultivar of Rehmannia glutinosa Libosch.
Field test and statistical analysis were applied.
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.
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.
比较地黄野生种质与栽培品种的性状差异。
采用田间试验和统计分析。
结果表明，与野生种质相比，栽培品种的株高和单株叶重显著降低，产量显著增加。叶长缩短。叶宽、叶中梓醇含量以及栽培品种中的多糖和还原糖含量增加不显著。而栽培品种中的梓醇含量和水提取物含量与野生种质相当。
地黄栽培品种的株高和单株叶重显著降低，但活性成分含量变化不明显。
