摘要： Arsenic is an important toxic substance in soil contamination, research of As accumulation and distribution in Camellia sinensis can explore adopting mechanism of tea plant to toxic substance and breeding of strong resistance varieties. In the research As content in root, stem and leaf part was detected on the condition of different concentration stress. The results showed that with the increase of treatment concentration relative change rate of tea plant was remarkable ascend. But, in root difference of five materials was most distinguished in low dose. In leaf when As concentration arrived 50 and 100mg/kg, difference of them was highly significant. Relative change rate from stem was not significant difference in all treatment.
