Description

Effects of monochromatic radiations between 300 nm and 700 nm on pycnidium formation were examined. Primordia of pycnidia were formed under darkness and irradiation of light was required for the formation of mature pycnidia with spore horns. The effective wave region was near ultraviolet radiation shorter than 370 nm. Radiation of 300 nm was the most effective for stimulating spore horn formation. On the contrary visible radiations between 400 nm and 700 nm showed more or less suppressive effect on the formation of mature pycnidia.
