| 摘 要： | 目的 :通过对不同半夏居群3种化学成分的比较研究 ,以期为半夏遗传多样性的研究提供依据。方法 :以3种化学成分为检测指标 ,对栽培在同一生境下的6个半夏居群进行了动态比较分析。结果与结论 :半夏各居群间 β-谷甾醇、缬氨酸及精氨酸含量存在着很大的差异 ,不同采收期其含量也存在有较大的差异 ,但从3种成分的平均含量来看 ,各居群均以秋收者为高。 |
| 关 键 词： | 半夏 居群 化学成分 β-谷甾醇 氨基酸 遗传多样性 |

| Abstract: | OBJECTIVE: To study the genetic diversity of Pinellia ternata. on the chemical composition. METHOD: Fifteen populations of Pinellia ternata. originated mostly from middle and lower reaches of Yangtze River valley were collected and cultivated in Weigang Experimental Farm of Nanjing Agricultural University with same cultural conditions, and contents in three types of index chemicals extracted from tubers of the populations have been compared continuously. RESULT AND CONCLUSION: The difference in contents of beta-sitosterol and Val and Arg extracted from tubers of the populations has been observed, and those contents are also different with harvesting time. But the mean contents of each of the three types of chemicals in autumn are all higher than those in summer respectively. |
