Effect of light quality on development of fruiting bodies of Panus fragilis

Abstract

Under a system that permits mass screening of mycelia within bands of the visible spectrum, fruit bodies initiated and developed in two light bands (387-400nm and 425-430nm) in axenic culture. Either or both of these light bands will trigger fruitbody initiation at as low an energy level as 0.2 K (1 K = 1,000 microwatts/cm2). Maturation of sporocarp and hymenium requires an energy level of no less than 1.8 K in at least one of these two bands, and consistent production of mature sporocarps requires 3.0 K at one or both peaks. The presence or absence of energy in other wavelengths of the visible spectrum has no detectable effect on either the initiation or maturation of the sporocarp.
