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.

研究了可见光波长对植物病原菌Colletotrichum acutatum和Fusarium fujikuroi的萌发，菌丝径向生长和分生孢子产生的影响。两种真菌均在黑暗的马铃薯葡萄糖琼脂培养基（PDA）上（对照）或在连续的白，蓝，绿或红光下在PDA上生长。另外，来自每个处理的分生孢子暴露于UV辐射。两种植物致病真菌的发芽和生长均不受任何处理的影响。当真菌在白光和红光下生长时，a形衣藻产生更多的分生孢子。富士黑狐在黑暗中产生更多的分生孢子。的公差，以不同上两个不同的明暗处理产生的分生孢子的UV辐射C. acutatum和F.苗病菌。当在白光下生产时，Acutatum的分生孢子对紫外线辐射的耐受性比在蓝光和绿光下至少高30％，比在黑暗中产生的分生孢子的耐受性至少高20％。分生孢子C. acutatum红光下制备是最少宽容。F.fujikuroi的分生孢子在白色和蓝色光下产生的分生孢子比在黑暗，绿色和红色光下产生的分生孢子至少多30％的紫外线耐受性。总之，在不同光照和黑暗条件下，两种真菌的发芽和生长均没有差异。但是，分生孢子的生产和紫外线辐射均存在显着差异。
