Metabolic response of Taxus baccata L. to Pestalotipsis funerea Desm. in dependence of environmental conditions

Abstract

One of the reasons of yew shoot blight observed in the garden and park plantations was the infection with <i>Pestalotiopsis funerea</i> fungus. Leaves with extensive disease symptoms have been found to have metabolic disturbances induced by this pathogen. Activation of oxidative stress enzymes, i.e. catalase and peroxidase, points to the possibility of inducing defense responses. Among factors modifying the degree of plant affection under natural conditions, the level of nitric nutrition as well as light conditions may play an important role.
