川芎苓种等级划分与植物生长发育的相关性研究
首发时间:2014-12-02
摘要:目的 进行川芎苓种分级标准的研究,对比不同等级川芎苓种对其植株生长发育的影响。方法 根据川芎道地产区长期的传统等级划分经验,将一~三个等级的苓种进行田间实验,并在川芎生长的6个时期(苗期、茎发生和生长期、倒苗期、二次茎叶发生期、抽茎期和根茎膨大期)进行田间生长发育观察。 结果 不同等级苓种对川芎的生长有显著性的影响,并且在不同生长期其影响有差异,一、二等苓种的川芎在植株生长发育上明显优于三等苓种的川芎。结论 本研究结果为川芎苓种质量分级标准提供了参考依据。

Study on relativity between Chuanxiong Lingzhong grades and tis growth
Abstract:Object Classification criterion of Lingzhong is studied by comparing influences of Lingzhong of different grades on its growth. Method Field testing is made about Lingzhong from 1~3 grades according to traditional experience of criterion classification. Observe its growth condition during its six different growing period(seedling stage, stem growth and development stage, leaves withering stage, second stem and leaves growing stage, stooling stage and rhizome expanding stage). Results Grades significantly influenced its growth and the influence effect varies at its different growth period. The first and the second grades apparently excel the third grade at Chuanxiong's growth. Conclusion The results provide references for the quality classification criterion of Chuanxiong Lingzhong.
Keywords: pharmacognosy Chuanxiong Rhizoma Lingzhong Grades classification Growth Relativity
