[Correlation and path analysis of artemisininum content and related factor on Artemisiae annie in Three Gorges reservoir area].
OBJECTIVE
Study on the correlation and path analysis of artemisininum comtent and related factor on Artemisiae annie. In order to obtain high artemisininum content Artemisiae annie.


METHODS
On the natural condition, choose 36 area where Artemisiae annie growth in three gorges reservoir area. The related factor on artemisininum content are studies through correlation and path analysis.


RESULTS
The artemisininum content had significant correlations with biomass, over cover degree, K, P, and N in soil. P in soil had the nost positive influence on the artemisininum content with the direct path coefficinent 0.3439, over cover degree had the nost negative in fluence on the artemisininum content with the direct path coefficient -0.1421. The influence order of other factor was N in soil (0.3180), K in soil (0.2352), biomass ( -0.0084), and plant height (-0.0347).


CONCLUSIONS
Artemisininum content in Artemisiae annie leaves are correlated with biomass, over cover degree, K in soil, P in soil, N in soil.
