Abstract

Abstract: Tea anthracnose fungi, Gloeosporium theae-sinensis, can produce pathogenic exo-toxin, which induced the lesions of tea leaves and the symptoms being similar to those resulted from G. theae-sinensis in the fields. The cultural filtrate of G. theae-sinensis was used to toxin bioassay, so as to make a study of the optimum conditions for toxin-producing and characteristics of toxins. The optimum toxin-producing conditions were as follows: pH 5.0, and 25℃ cultivating for 16 days in the manner of vibration with Czapek-Dox liquid medium. The method of immerging the tea shoots into toxin solution was appropriate for the bioassay of toxins.

Key words: gloeosporium theae-sinensis, bioassay, cultural conditions, toxin
