Abstract
Octanal is a potential alternative to chemical fungicides in controlling postharvest disease of citrus fruit. In this study, the antifungal activity and the underlying mechanism of octanal against spore germination of Penicillium digitatum, one of the main postharvest pathogens in citrus, were investigated. Results showed that octanal at different concentrations (0, 0.25, 0.50, 1.00, 2.00 μl/ml) inhibited the growth of P. digitatum spores in a dose-dependent manner. The morphology and the membrane permeability of P. digitatum spores were visibly altered by 0.25 and 2.00 μl/ml of octanal. Meanwhile, octanal decreased the total lipids contents of P. digitatum spores, indicating that the membrane integrity is damaged. Furthermore, octanal apparently induced the massive accumulation of total malonaldehyde (MDA) and the reactive oxygen species (ROS). An increase in the activities of lipoxygenase (LOX), NADH oxidase, superoxide dismutase (SOD), catalase (CAT), and peroxidase (POD) was also observed. These results suggested that a membrane damage mechanism involving membrane peroxidation might contribute to the antifungal activity of octanal against P. digitatum spores.
