Influence of high doses of manganese, copper, zinc and boron on some legumes

Journal Article:

Abstract

Macroscopic and microscopic examinations showed the following symptoms of an excess in trace elements: (1) High doses of manganese (50-150 ppm) cause dark patches (chloroplast accumulation) in young leaves, and necrosis of the leaf margin (MnO/sub 2/ accumulation) in older leaves. The roots become brown and die off. Roots newly formed in compensation are strikingly light-colored. (2) High doses of copper (5-40 ppm) cause iron deficiency chlorosis. A large number of side roots develop in quick succession as a result of damage to the root apex, so that a thick tangle of roots is formed. (3) High doses of zinc (50-150 ppm) bring about dark green, very brittle young leaves with very high ZnO content. The older leaves become red and then yellow. The roots remain stunted because of inhibited growth in length. (4) High doses of boron (30-90 ppm) cause a leaf necrosis which proceeds in the sequence tip, margin, lamina. The roots are not affected in any characteristic way. They become brown and die off.
