ABSTRACT

<p><b>OBJECTIVE</b>To 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.</p><p><b>METHOD</b>A. annua were cultivated in pots with Cd concentration at 0.5, 1.5, 4.5 mg x kg(-1) level, respectively.</p><p><b>RESULT AND CONCLUSION</b>The 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.</p>
