在自然生长条件下,选取三峡库区36个不同来源地的野生青蒿作为研究对象,对影响青蒿花蕾青蒿素含量相关因素进行灰色关联分析。结果表明,土壤碱解N和P含量是影响三峡库区野生青蒿的青蒿素含量的最主要最明显的因素。三峡库区野生青蒿花蕾青蒿素含量主要受土壤营养状况影响。
Under the conditions of natural growth, we selected wild A. annua from 36 different sources in the Three Gorges Reservoir Area as the research object, and analyzed the related factors affecting the artemisinin content of the A. annua flower bud. The results showed that the contents of N and P in soil were the most obvious and important factors affecting the artemisinin content of wild A. annua in the Three Gorges Reservoir Area. Artemisinin content of wild Artemisia annua flower buds in the Three Gorges Reservoir Area is mainly affected by soil nutrient status.
