Abstract: | Detached Vitis vinifera (cv Chardonnay) inflorescences were inoculated with spore suspensions of either Colletotrichum acutatum or Greeneria uvicola at 25°C, and a combination of light microscopy, scanning electron microscopy and plating out of inoculated flowers on to dichloran rose bengal chloramphenicol agar was used to investigate the time frame for infection. Colletotrichum acutatum infection commenced within 2 h of inoculation, while infection by G. uvicola commenced between 12 and 18 h postinoculation. All parts of the flowers were infected by both fungi. |
