  • Abstract Copper-treated rice seeding (Oryza sativa cv. Tainung 67 and Taichung native 1) showed significant inhibition in rice root growth, and an enhancement in POD activity. POD within Tainung 67 rice roots might synthesize more lignin in Cu-treated tissue. Meanwhile, the decrease of H2O2 levels is accompanied with the enhancement of POD activity in Cu-treated tissues. The increase in POD activity induced by Cu might remove excess hydrogen peroxide serving a detoxifying role and synthesizing more lignin for protection. In Taichung native 1 rice cultivar, high amounts of H2O2 accumulated in Cu-treated tissues could be due to the less amounts of POD induced by Cu. In response to Cu treatment, the Taichung native 1 cultivar also synthesizes a little lignin, and is more Cu-sensitive. Therefore, The Tainung 67 cultivar is more tolerant to Cu than Taichung native 1.
