摘要: The pesticides used to tackle potato pathogens, including bacteria, are environmentally damaging, so more sustainable treatments needed. Because plant defense-related hormones such as methyl jasmonate and salicylic acid the elicitor chitosan can stimulate defense systems, effect of these compounds was tested by adding them a watering solution 2 days before inoculating two S. tuberosum cultivars with either Pectobacterium carotovorum strain 5890 or P. atrosepticum 889. Growth production several phenolic were determined in treated untreated plants, inoculated not. virulent than 5889 reflected higher levels plants. hormone offered most protection against bacteria without interfering growth. plants produce accumulate secondary metabolites for infection, accompanied less pathogen damage resistance.
