Role of sulphur availability on cadmium-induced changes of nitrogen and sulphur metabolism in maize ( Zea mays L.) leaves

The interactions between sulphur nutrition and Cd exposure were investigated in maize ( Zea mays L.) plants. Plants were grown for 12 days in nutrient solution with or without sulphate. Half of the plants of each treatment were then supplied with 100 μM Cd. Leaves were collected 0, 1, 2, 3, 4 and 5...
