| 以7份管花肉苁蓉种质为材料，分析了不同种质的药用成分、单株干重和农艺性状差异。结果表明：1）7个种质的松果菊苷含量为21.09%~50.86%，差异显著，种质Ⅱ > 种质Ⅳ > 种质Ⅲ > 种质Ⅴ > 种质Ⅶ > 种质Ⅰ > 种质Ⅵ；毛蕊花糖苷含量为2.08%~3.28%，种质Ⅱ > 种质Ⅰ > 种质Ⅳ > 种质Ⅲ > 种质Ⅴ > 种质Ⅶ > 种质Ⅵ。2）7个种质的单株干重为179.1~443.0 g，种质Ⅰ > 种质Ⅱ > 种质Ⅳ > 种质Ⅵ > 种质Ⅲ > 种质Ⅴ > 种质Ⅶ。3）7个种质的单株种子重为14.9~8.9 g，种质Ⅱ > 种质Ⅰ > 种质Ⅳ > 种质Ⅵ > 种质Ⅶ > 种质Ⅴ > 种质Ⅲ；种子萌发率为60.7%~38.0%，种质Ⅱ > 种质Ⅶ > 种质Ⅳ > 种质Ⅰ > 种质Ⅵ > 种质Ⅴ > 种质Ⅲ。结果说明，不同种质的药用成分含量和单株干重差异显著。种质Ⅱ具有松果菊苷含量和毛蕊花糖苷含量高，单株干重大，种子萌发率高的特征，是最有开发潜力的优良种质。 |

| Abstract: |
| The subject of the study was to investigate the effects of different Cistanche tubulosa germplasms on medicinal component contents,dry weight per plant and agronomic characteristics.The results showed that:1) The highest echinacoside content was 50.86% and the lowest was 21.09%.The verbascoside content of those seven germplasms was between 2.08% to 3.28%. The germplasm Ⅱ had the highest echinacoside and verbascoside content which reached 54.14%,and the germplasm Ⅵ had the lowest echinacoside and verbascoside content which was 23.18%.2)The dry weights per plant of these seven germplasms were ranged between 179.1 to 443.0 g.The germplasm Ⅰ had the highest and the germplasm Ⅱ had the second highest dry weight.3) The germplasm Ⅱ had the highest rate of larger seed and its germination rate was 39.25% to 60.7%.The lowest number of lager seed and germination rate were 15.88% and 38.0% which appeared in germplasm Ⅲ.In conclusion,the germplasm Ⅱ showed the highest echinacoside and verbascoside content,dry weight per plant and germination rate among the seven germplasms. |
