摘要: Bacterial wilt caused by Ralstonia solanacearum is a devastating plant disease affecting several economically important crops. To trigger plant-mediated systemic resistance against the pathogen, silicon and rhizobacteria strain Bacillus pumilis were applied as elicitors. The impact of each elicitor in induction was evaluated individual or dual application pathogen inoculated tomato genotypes. Application B. pumilis significantly reduced bacterial incidence 50.7 26.7%, respectively, King Kong 2 genotype (moderately resistant) 31.1 22.2%, L390 (susceptible) but elicitors did not. responsive lipoxygenase (LOX) activity decreased silicon-treated plants no significant difference detected treated-pathogen compared to control. In addition, non-significant increases peroxidase (PO) phenylalanine ammonia lyase (PAL) observed either silicon/B. treated plants. However, PO, PAL LOX activities declined during due antagonistic effect two pathways triggered Therefore, separate recommended best strategy for with being stronger inducer than B. pumilis.
