Paper Title:
Cadmium Accumulation and Antioxidative Defenses in Leaves of Zea mays L.
  Abstract

Corn (Zea Mays L.) seedlings were in four cadmium (Cd) levels of 0-1mg/L in a hydroponic system to analyze the antioxidant enzyme system, Cd content in the shoots and roots and growth responces in the leaves of corn. There was a significant increase in malondialdehyde (MDA) concentration from Cd 0mg/L to 1mg/L, and peroxidase (POD) and catalase (CAT) activities in the leaves of corn subjected to 0-1mg/L Cd. However there was a significant decrease in superoxide dismutase (SOD) activities subjected to 0-1mg/L Cd. This indicated that Cd stress induced an oxidative stress response in corn seedlings, characterized by an accumulation of MDA, decrease in activities of SOD and increase in activities of POD and CAT. Root and leaf Cd contents of corn increased with their exposure Cd level, and the highest Cd concentration occurred in roots, followed by leaves.
