摘要：

Five strains of Pseudomonas fluorescens and Trichoderma spp., found efficient in suppressing root rot of black pepper (Piper nigrum L.), caused by the pathogen Phytophthora capsici, were tested in vitro for their efficacy in lysing the cell wall of Phytophthora capsici. The antagonists produced mycolytic enzymes viz. beta-1,3-glucanases, beta-1,4-glucanases and lipases. Variations among the strains were found for the production of these enzymes. Strains of Pseudomonas fluorescens caused cytoplasmic coagulation in the mycelium of Phytophthora capsici when they were cultured together. The findings demonstrate a mechanism of antagonism by Pseudomonas Fluorescens and Trichoderma spp.
