摘要
目的 :研究鱼腥草不同居群产量以及不同时期主要药用成分含量等变化规律 ,为鱼腥草适时采收、新品种选育提供依据。方法 :田间采用拉丁方试验设计 ,定期取样测定主要药用成分含量及单位面积地上部分鲜重 ,收获时测定小区产量并进行方差分析。结果 :鱼腥草不同居群产量差异极显著 ,不同居群甲基正壬酮含量和单位面积甲基正壬酮总量变化趋势也不同。结论 :邛崃和望渔野生居群综合性状较好 ,具推广应用价值。
Objective: To study the yield of different Houttuynia cordata and the changing regularity of their main officinal components in different periods, and provide a basis for harvesting in good time and breeding new varieties. Method: The main officinal composition and wet weight of overground parts per acreage of different accessions were determined periodically. The plot yields were tested when harvested and analyzed by analysis of variance. Result: The difference of the yields of different accessions was significant. The varying tendency of the content of main officinal component methyl nonyl ketone and its total content per acreage of different accessions were different. Conclusion: The integrate characters of Qionglai and Wangyu wild accessions are relatively better, worthy to be widely applied in production.
