Title: Effects of cadmium and zinc on ozone-induced phytotoxicity in cress and lettuce

Abstract

Cadmium or zinc solutions were applied to the foliage or roots of lettuce (Lactuca sativa L. cv. Grand Rapids) and cress (Lepidium sativum L. cv. Fine Curled) at concentrations of 100 parts per million (ppm) every four days for several weeks. Four weeks after sowing, plants were fumigated with 35 parts per hundred million (pphm) ozone, for 6 hours. Cress plants which had received root application of cadmium showed markedly increased ozone-induced phytotoxicity in terms of visible leaf damage and pigment degradation; in lettuce only pigment degradation was evident. There was less effect of zinc or foliar-applied cadmium on ozone phytotoxicity.
