[Characteristics of element contents and their influence factors in Codonopsis tangshen].
OBJECTIVE
To study the characteristics of element contents and the influencing factors in Codonopsis tangshen.


METHODS
The contents of elements were determined and the data was statistically analyzed.


RESULTS
The variation coefficients of elements in C. tangshen were lower than those in soil, and variation coefficients of C. tangshen from different habitats were lower than 50%.


CONCLUSIONS
The absorption of nutritional elements in C. tangshen was related to content and condition of soil nutrients, and climate etc.
