Pot experiment was conducted to investigate the difference in cadmium (Cd) accumulation and distribution of rice plant between two types of rice varieties, high Cd content type (HCT) and low Cd content type (LCT). The results showed that the difference in Cd concentration in root and stem between two types of rice was inapparent, but that in brown rice was significant. Compared to HCT, Cd accumulation in roots and leaves of LCT was indistinctively less, but Cd accumulation in stems (stem-Cd) and the ratio of stem-Cd to whole plant-Cd of...
