目的确定青蒿素储存部位并为高青蒿素含量黄花蒿植株筛选提供选择指标。方法应用组织化学方法确定青蒿素的储存结构,应用统计学方法确定储存结构腺毛状分泌腺密度与青蒿素含量的相关性。结果青蒿素储存于腺毛状分泌腺(BGT)和T-型网状分泌腺(NTFT)中,在叶中腺毛状分泌腺的密度与青蒿素含量正相关。结论腺毛状分泌腺密度可作为高青蒿素含量黄花蒿育种筛选指标。

Object To determine the histochemical location deposited artemisinin and to provide selection character for screening of Artemisia annua L.which contains rich content of artemisinin.Methods Artemisinin was located by the histochemical method and then statistical method was used to ascertain the correlation between the content of artemisinin and the density of biseriate glandular trichemes(BGT).Results Artemisinin is located in both BGT and nonglandular T-shaped filamentous trichomes(NTFT) in A.annua leaves.The content of artemisinin had a positive correlation with the density of BGT in A.annua leaves.Conclusion High density of BGT in foliar tissue might be considered as one of the selection characters for the screening of A.annua with rich content of artemisinin.
