Abstract:
Taking tomato as material,5 different concentration of benzoic acid (0，100，150，200，250 μmol/L) were set to stress tomato seeds,sodium nitroprusside (SNP),sucrose,ascorbic acid were added to explore the germination of tomato allelopathy and eliminate allelopathy effect.The results showed that with the increasing concentration of benzoic acid,tomato seed germination,germination rate,germination index,vigor index,allelopathic effect index showed decreasing trend,indicating that the acid inhibited germination of tomato seeds.Exogenous 50 μmol/L sodium nitroprusside,0.25% sucrose had the better relaxation effect on benzoic acid stress of tomato seed germination,but 50 μmol/L sodium nitroprusside inhibited radicle growth.0.25 mmol/L vitamin C had relaxation effect on inhibited tomato seed germination and radicle growth under benzoic acid.
