Abstract

We investigated the interaction of elevated CO₂ and/or (Ozone) O₃ on the occurrence and severity of aspen leaf rust (Malampsora medusae Thuem. f. sp. tremuloidae) on trembling aspen (Populus tremuloides MIchx.) Furthermore, we examined the role of changes in leaf surface properties induced by elevated CO₂ and/or O₃ in this host-pathogen interaction.
