abstract = "The effects of the visible light wavelengths on germination,
mycelial radial growth, and conidial production of the plant
pathogens Colletotrichum acutatum and Fusarium fujikuroi were
studied. Both fungi were grown on potato dextrose agar medium
(PDA) in the dark (control) or on PDA under continuous white,
blue, green or red light. In addition, the conidia from each
treatment were exposed to UV radiation. The germination and growth
of both plant pathogenic fungi were not affected by any of the
treatments. C. acutatum produced more conidia when the fungus grew
under white and red light. F. fujikuroi produced more conidia in
the dark. The tolerances to UV radiation of conidia produced on
different light and dark treatments differed for both C. acutatum
and F. fujikuroi. Conidia of C. acutatum were at least 30% more
tolerant to UV radiation when they were produced under white light
than under blue and green light and at least 20% more tolerant
than conidia produced in the dark. Conidia of C. acutatum produced
under red light were the least tolerant. Conidia of F. fujikuroi
produced under white and blue light were at least 30% more UV
tolerant than conidia produced in the dark, green, and red light.
In conclusion, no differences were found for germination and
growth for both fungi under different light regimes and dark;
however, significant differences occurred both in production and
UV radiation of conidia.",
