Abstract

The polysaccharide component of VD-toxins of 5 strains of V.dahliae with different pathogenicity to cotton plant was treated with β-glucosidase (at 37℃,6 hrs).It showed that the treated VD-toxins lost wilting activity to seedlings of cotton (DPL-15).The result suggests that the polysaccharide component of VD-toxins is not important in wilting activity to the cotton plant.
