【 摘 要 】

This study evaluated effect of single salicylic acid (SA), calcium ion (Ca2+) or their combination on disease resistance of tomato (Lycopersicon esculentum cv. L402) against fungal pathogen Botrytis cinerea (B. cinerea). Elicitation with single SA, Ca2+ or their combination, particularly combined treatment, caused a remarkable increase (p<0.05) in accumulation of hydrogen peroxide (H2O2) and superoxide anion (O2-), phenylalanine ammonia-lyase (PAL) activity, expression level of PR (pathogenesis related protein) gene in tomato plants and resulted in elevating resistance against B. cinerea. These results suggested that SA and Ca2+ played important role in induction of disease resistance against B. cinerea. Therefore, SA and Ca2+ might have potential to control gray mold disease of tomato.
