| 摘 要： | 对青蒿在不同海拔的生长及青蒿素累积动态变化进行试验研究,结果表明,不同海拔青蒿植株高度、生物量及青蒿素的累积都有显著差异,海拔1000m以下的青蒿生长快,青蒿素含量及产量也高.青蒿素含量及产量与海拔高度呈负相关,与生育期日均温呈正相关,青蒿素产量与植株含水量呈正相关,青蒿素含量与植株含水量呈负相关.综合分析表明,海拔1000m以下适度高温、低湿环境有利于青蒿素的累积.

| Abstract: | Authors examined the dynamic variations of A rtemisia annua L growth and associated artemisinin accumulation at different altitudes.Study results showed that there was a significant difference in plant height,biomass,and artemisinin accumulation in the context of altitudes.For example,at an altitude below 1000m,Artemisia annua L.grew more quickly,with a higher artemisinin content and yield.Both Artemisinin content and yield were positively correlated with altitude,though negatively correlated with average d... |
