Abstract:

Under shading and normal sunshine, two artemisiae annie were selected to study the effect of shading stress on biologic traits in artemisiae annie. The experiment was conducted with three replications . The main results were summarized as follows : The dry weight of shoot, dry weight of root system, plant height, leaf area, chlorophyll content, arotenoid content and artemisinine content among artemisiae annie decreased under shading sunshine, comparing with normal sunshine. Differences of them in artemisiae annie were significant between shading and normal sunshine. The artemisinine content was significant correlation with dry weight of shoot, chlorophyll content, and arotenoid content at 1%.
