| Abstract: | From 1985 to 1988, 567 individual plants of watermelon were collected in three regionsand infected in different degrees. The pathogen of the diseased plants was proved to beFusartum oxysporum f. sp: ntveum using the routine method. To obtain their toxin filtrates,30 single spore strains selected were cultured in liquid medium. Watermelon seedlings weresoaked in the toxin filtrates of different strains to determine their pathogenicity, and seed-lings were planted in the pots with the soil inoculated with different strains as control. Onthe basis of the pathogenicity the strains were divided into three types, the strong, middleand weak pathogenicity strains. The results of the two treatments were similar. It can beused to determine the pathogenicity of different strains with toxin filtrates. |
