An effective suppression of Dutch elm disease symptom development was observed in elms resistant to the non‐aggressive strain of Ophiostoma ulmi, but not to the aggressive strain, after a preventive treatment by this non‐aggressive strain. Anequally effective isolate of Verticillium dabliae suppressed symptom development even in the very susceptible field elm (Ulmus carpinifolia). Induction of resistance is proposed for the major mechanism explaining these and earlier experiments. The primary stimuli initiating a resistance reaction are unknown, but the intermediates of the univalent reduction of oxygen may play a role. In an experiment the activities of two groups of enzymes involved in the catalytical scavenging of these radicals, superoxide dismutase and peroxidase, were monitored, but no correlation with induction of resistance was observed. Resistant elms showed the highest activities, probably reflecting a more effective defence against radicals than susceptible ones.

The levels of peroxidase activity in roots of non‐infected tomato plants resistant to Verticillium dahliae Kleb., were found to be considerably higher than those in the roots of susceptible plants. Similar differences were found in the leaves but were not significant as in the roots. Peroxidase activity increased in leaves, stems and roots of both susceptible and resistant plants after infection with V. dahliae. The ratio of the increase in leaves and roots of susceptible plants was greater than those of resistant plants. A positive correlation was found between the peroxidase activity in the roots of eleven cultivars/breeding lines and presence of Ve gene.

“…Oxidative metabolism, accompanying TMV infection, can cause an in crease in host phenylalanine ammonia-lyase (Conti et al 1974), polyphenol oxi dase and peroxidase (Weststeijn 1976) with a decrease in o-dihydric phenols, especi ally chlorogenic acid (Farkas et al 1960). With respect to fine structural alter ations within virus infected host tissue, Betto et al (1972) suggest that the chloro plast may well be a possible site for viral multiplication.…”
