【Abstract】 The determination of induced resistance showed that six inducing strains of Fusarium could induce resistance of corn to corn stalk rot. The induced protection caused by F 1 for Pythium raminicola was the best, the effects of F 1 injection and soil inoculation were 100% and 88% respectively. The induced protection caused by F 5 for F. graminearum was the best, the induced effects of the forenamed methods were all 100%. The effect of soil inoculation before sowing was the best and its protection period could be kept longer, which could improve the agronomic character of corn.更多还原
