Abstract
AbstractTrichothecium roseum causes decay in muskmelons, apples, tomatoes and mangoes, which leads to economic losses. In this study, we investigated the effect of sodium silicate on the growth of T. roseum and the cell wall‐degrading enzymes (CWDEs) secreted by the hyphae. The results indicated that sodium silicate significantly inhibited mycelial growth and spore germination of T. roseum. The sodium silicate treatment also retarded the secretion of several CWDEs, including pectate lyase (PL), polygalacturonic acid transeliminase (PGTE), pectin methyltranseliminase (PMTE), pectin methylgalacturonase (PMG), polygalacturonase (PG), cellulase (Cx) and β‐glucosidase. These results suggest that sodium silicate exerts its effects on T. roseum through direct inhibition of its growth and secretion of CWDEs.
