The production of 8-ketotrichothecenes, deoxynivalenol (DON), nivalenol (NIV), and their monoacetyl derivatives was studied in rice and corn cultures using 8 isolates of Fusarium graminearum which were obtained from corn and barley samples. Higher concentrations of trichothecenes were produced on rice than corn, and production of the toxins on rice was enhanced by growing the fungi at $25^{\circ}C$. The isolates were used for evaluation of toxin production and pathogenicity after artificial inoculation to 5 corn and 3 barley cultivars. The kinds and the relative amounts of trichothecenes produced in cultures were consistent with those in infected kernels of corn and barley with some exceptions. As for DON chemotypes, the ratios of 15-acetyl-DON to 3-acetyl-DON were varied among the pathogen-cultivar interactions. The corn and barley cultivars showed the significant differences of resistance to the Fusarium isolates in disease severity and seedling blight, and resistance ranking to the different isolates was varied. However, significant correlations were observed between the total concentrations of trichothecenes in infected kernels of corn and barley and pathogenicities of the Fusarium isolates to the hosts.

중국으로부터 수입한 68개의 옥수수시료에서 Fusarium진균독소의 오염을 조사하였다. 수입옥수수에서 eoxynivalenol(DON), 15-acetyldeoxynivalenol(15-ADON), 3-acetyldeoxynivalenol(3-ADON) 및 nivalenol(NIV) 등 4가지의 8-ketotrichothecene이 검출되었다. 또한 zearalenone(ZEA), fumonisin $B_1(FB_1)$, fumonisin $B_2(FB_2)$ 그리고 fumonisin $B_3(FB_3)$도 검출되었다. DON, 15-ADON, 3-ADON, ZEA 그리고 $FB_1$이 주요 오염독소였으며, 이들 독소의 평균오염농도는 각각 277, 34, 37, 39, 그리고 123 ng/g이었다.
