Abstract: The effect of different colors of light on radial growth of P. eous was studied under in vitro conditioninMushroom Research Laboratory Department of Plant Pathology, College of Agriculture, IGKV, Raipur at 2011-12. The radial growth of P. eous in blue light with 455-492 nm wavelength favor highest significant growth (88.50 mm) followed by Red wavelength 622-780 nm with (78.50 mm ) and pink wavelength 600-650 nm with (76.50 mm) growth . However radial growth P. eous were recorded at par in purple wavelength 390-455nm (65.50 mm), yellow wavelength 577-597nm (68.50 mm), transparent 1520-1580 nm (70.50 mm) as compare to control (65.50 mm). The least radial growth was observed in green wavelength 492-577nm (43.50 mm).The Mycelial character of wavelength 455-492 nm was whitish pink dense cottony mycelial growth with regular margin and wavelength 622-780 nm was White dense mycelial growth with regular margin. The Mycelial character of wavelength 492-577 nm was white cottony mycelial growth with regular margin. This wavelength shows very poor growth.
