Abstract
High Resolution Image Download MS PowerPoint Slide Common bacterial blight (CBB), caused by Xanthomonas axonopodis pv. phaseoli, severely limits common bean production worldwide. This study evaluated whether induced resistance using acibenzolar- S -methyl (ASM) and harpin protein (HRP) can mitigate disease severity while maintaining plant physiological performance and yield. Two cultivars contrasting in CBB susceptibility (IAPAR 31 and IPR-Colibri) were treated with elicitors and inoculated with the pathogen. Disease severity, gas exchange, peroxidase activity, phenolic content, and yield components were assessed. Both ASM and HRP significantly reduced disease severity, with reductions of up to 79% in the susceptible cultivar. Elicitor treatments enhanced peroxidase activity and phenolic accumulation, indicating the activation of plant defense responses. ASM also improved photosynthetic parameters, including CO 2 assimilation and water use efficiency. However, no significant increases in yield or yield components were observed. These results indicate that although elicitors effectively induce resistance and improve physiological responses, this does not necessarily translate into productivity gains, highlighting a trade-off between defense activation and plant growth.
