Abstract
An action spectrum for photoinduced conidium formation in the fungus Botrytis cinerea Pers. ex Fr. was determined by exposing colonies to monochromatic radiation obtained from a diffraction grating monochromator. Wavelengths longer than 355 nm were ineffective even after exposures of 8 hours at intensities of 4,068 to 8,276 erg per cm2 per second. Colonies were exposed at 22.5 C from 226 to 355 nm at about 5 nm intervals. Three prominent peaks of effectiveness occurred at about 231, 268, and 283 nm, and there was also a minor peak at about 303 nm. The most effective wavelength for inducing sporulation was 231 nm; it was 25% more effective than the second most effective wavelength (283 nm).
