Qualitative and quantitative effects of radiation on pycnidial formation by Dendrophoma obscurans
Keyword(s):
Cultures of Dendrophoma obscurans grown on a 10:2 glucose: casein hydrolysate medium require radiation for sporulation. Far-ultraviolet (253.7 nm), near-ultraviolet (300–425 nm), and blue radiation (400–525 nm) were effective in initiating pycnidial formation. Exposure of cultures to radiation from 500 to 850 nm did not induce sporulation. Pycnidial formation was found to be photoinduced and age dependent. Low intensities of near-ultraviolet radiation administered over long durations were more effective than high intensities of short durations for inducing pycnidial formation.
