Abstract: Cassava is one of the most important crops in tropical regions. Due to multiple mining activities, arsenic (As) pollution becomes a serious problem in planting lands. In this study, a hydroponic experiment was carried out to ascertain the influence of As on three cassava cultivars (sc12, 8229 and sc6068). The three cassava cultivars showed different accumulation and response characteristics to As. The 8229 was apt to accumulate As in the root. Low As concentration promoted the growth of 8229 but inhibited that of sc12 and sc6068. This indicated that 8229 is more tolerant to As than the other two cassava cultivars. The malondialdehyde (MDA) of the three cassava cultivars, both in roots and leaves, were elevated with increasing As concentration. This study could be a reference for cassava planting in safety.
