摘要： Chalcones are a class of flavonoids possessing antimicrobial properties and have potential for use as coatings of plant products for the control of postharvest diseases. The effects of 2 ',4 '-dichloro-chalcone on the in vitro growth and in vivo pathogenicity of Fusarium tricinctum and Trichothecium roseum were investigated. First, 1 mu M of 2 ',4 '-dichloro-chalcone strongly inhibited the mycelial growth and conidial production of F. tricinctum (32.3%) and T. roseum (65.2%) in vitro. Meanwhile, the cell membrane permeability was increased by 25% and 22.5% and the accumulation of reactive oxygen species was increased by 41.7 and 65.4%, respectively, of F. tricinctum and T. roseum. This treatment also significantly inhibited the total respiration rate and activated the cyanide-resistant respiratory pathway in both pathogens. The expression level of AOX was enhanced in F. tricinctum and T. roseum by 52.76 and 39.13%, respectively. This treatment also significantly inhibited the expansion of potato dry rot from F. tricinctum (48.6%) and apple rot spot from T. roseum (36.2%). Therefore, 2 ',4 '-dichloro-chalcone has potential use as an alternative safety method in the control of postharvest diseases by F. tricinctum and T. roseum in agricultural practices.
