Uniconazole-induced changes of stress responses of Vicia faba : polyphenole oxidase activation pattern serves as an indicator for membrane stability

摘要: Influence of uniconazole and different salt concentrations on growth development broad bean ( Vicia faba L.) were investigated. Addition to the irrigation water caused significant reduction plant but treated plants revealed better biomass. The number phenolic compounds in V. leaf extracts changed with age leaves, antioxidative potentials slightly lower. activity polyphenoloxidase its activation after plastid membrane desintegration by SDS lower plants. Further studies varying SDS-concentrations a remarkable difference disintegration pretreated This finding supports hypothesis that enhanced stress tolerance treatment is based physiological change thylakoid stability.
