  • Abstract Cd significantly inhibited the growth of both rice cultivars. The Tainung 67 cultivar is more tolerant to Cd than Taichung 1 cultivar after 48 h incubation in CdCl2 solution. The Cd tolerant cultivar—Tainung 67’s PODs in roots might synthesize more lignin in Cd-treatments. Meanwhile, the decrease of H2O2 levels is accompanied with the enhancement of POD activity in Cd-treated tissues. PODs here might also remove excess H2O2, thus serving detoxifying role and synthesizing more lignin for protection. In Taichung 1 cultivar, the accumulation of H2O2 in Cd-treated tissues could be due to the less amount of POD enhancement induced by Cd. In response to Cd treatment, the Taichung 1 cultivar also synthesizes little lignin, and therefore is Cd-sensitive.
