Abstract:
OBJECTIVETo study the accumulation and translocation of cadmium in the soil and Artemisia annua, and observe its effects on growth of A. annua and artemisinin content.
METHODA. annua were cultivated in pots with Cd concentration at 0.5, 1.5, 4.5 mg x kg(-1) level, respectively.
RESULT AND CONCLUSIONThe growth of A. annua was inhibited at all the Cd levels characterized by the decreases of biomass and agronomic parameters; Most of Cd was accumulated in the roots of A. annua, and the ratios of Cd concentrations in roots and aerial part were 1.8:1 and 2.3:1 at 1.5, 4.5 mg x kg(-1) Cd level, respectively. Artemisinin content increased significant at 0.5 mg x kg(-1) Cd level, but there were no significant changes comparing with control group other Cd levels.
