Summary
An action spectrum for photoinduced sporulation (conidia formation) in Trichoderma viride is presented. The detectable quantum efficiency was between 350 and 550 nm with peaks near 380 and 440 nm with a minimum at about 400 nm. Essentially no sporulation occurred at 254 nm or from 525 to 1100 nm. The half maximum response is reached with 6.6·10-10 Einstein/cm2 at 447 nm.
