Abstract

Soil supports the growth of a jute pathogen Colletotrichum gloeosporioides but only to a limited extent that of its antagonist Aspergillus versicolor. The growth of the sensitive pathogen is considerably checked by the antagonist in mixed soil culture although versicolin production could not be demonstrated within the limits of assay. Both the sensitive and the antagonistic organisms grow well in soil-compost medium and versicolin production by the latter is also enhanced. The antagonistic effect of Aspergillus versicolor on Colletotrichum gloeosporioides is expectedly more marked in soil-compost medium than in soil medium.

摘要

土壤支持黄麻病原菌胶孢炭疽菌（Colletotrichum gloeosporioides）的生长，但仅在有限程度上支持其拮抗菌杂色曲霉（Aspergillus versicolor）的生长。在混合土壤培养中，敏感病原菌的生长受到拮抗菌的显著抑制，尽管在测定限度内未检测到杂色曲菌素的产生。敏感菌和拮抗菌在土壤-堆肥培养基中均生长良好，且后者的杂色曲菌素产量也有所提高。杂色曲霉对胶孢炭疽菌的拮抗作用在土壤-堆肥培养基中比在土壤培养基中更显著。
