Effect of Excess Supply of Heavy Metals on Barley during Germination, with Special Reference to Catalase and Peroxidase

Nature volume 191, pages 726–727 (1961)Cite this article

Abstract

THE injurious effect of the excess supply of heavy metals on plant growth, among other factors, has been attributed to induced iron-deficiency1–3. Recently4–7, it has been shown that heavy metals such as cobalt, nickel, copper, molybdenum and chromium, when supplied in excess, depress chlorophyll and catalase ; in some instances peroxidase is also depressed. The repeated application of iron–ethylenediamine tetra-acetic acid to plants receiving the heavy metals mitigates the effect of heavy metals6 on chlorophyll, catalase and peroxidase.
