AuthorshipSCIMAGO INSTITUTIONS RANKINGS

    The objective of this experiment was to study the influence of light and temperature on uredospore germination of Puccinia psidii Winter. Two temperatures (18°C and 22°C) and five patterns of illumination (0, 4, 8, 16, and 24 hours of darkness) were tested. The results showed that the temperature of 18°C and 8 hours of darkness were the most favorable conditions for the uredospores germination.
