Abstract
IN the course of an investigation into the toxic effects of nickel on plants, it was found that the calcium content of nickel-toxic oat plants was consistently higher than that of healthy plants1. The absorption of other major nutrients, on the other hand, was reduced in the presence of nickel. In contrast, tomato plants showed a reduced content of all major elements, including calcium, when supplied with nickel in toxic amounts. The toxicity symptoms produced in both plants consist of chlorosis (of young leaves) accompanied by longitudinal necrotic striping (oat) or necrotic areas of the older leaves (tomato). Growth is reduced and root development arrested ; the roots become brown, with poor secondary-root production.
