Salicylic acid, salicyluric acid, and gentisic acid in plasma are specifically quantitated (ultraviolet detection at 313 nm) with an octadecyl silane reversed-phase chromatographic column by peak-height determination or by peak-height ratios (internal standard, o-methoxybenzoic acid). Sample preparation requires addition of an equal volume of methyl cyanide (with or without the internal standar...

to study the interaction effect of the salinity and salicylic acid on some morphological and physiological traits in clary sage (salvia sclarea), a pot experiment was conducted as factorial based on a completely randomized design with three levels of nacl and control (zero, 50, 100 and 150 mm), as the first factor and three levels of spraying the solution of salicylic acid and control (zero, 10...

Catharanthus roseus L. is an important medicinal plant producing several terpenoid indole alkaloids (TIAs) such as vincristine and vinblastine secondary metabolites with anticancer activity. The TIAs biosynthetic pathways are affected by biotic and abiotic stresses. In this study the effect of drought (7 days), salinity (150 mM NaCl), foliar spray of salicylic acid (10-5 M) and salicylic acid i...

among the environmental stresses, salinity is a major limiting factor in world legumes production is considered. in this study, sodium chloride and salicylic acid interaction on growth parameters were investigated in greenhouse with factorial arrangement in randomized complete block design with three replications. the plant consisted of three cultivars of lentil (kimiya, kermanshah and gachsara...

violet is one of the ornamental plants with a good value in landscaping and herbal medicine. salicylic acid is a signaling agent involving in secondary metabolite production. the aim of this study was to evaluate the physiological responses of violet flowers to exogenous salicylic acid. this experiment was conducted in the greenhouse, as a completely randomized design. salicylic acid was spraye...

abstract in recent years some research results have appeared that exogenous salicylic acid provided significant mitigation effect against salinity induced injuries in plants. an experiment was conducted to investigate the effects of salt stress and salicylic acid on radish (raphanus sativus l.) plants. after appearing first leaves, plants were treated by salicylic acid (0.2 mm) for 3 days and n...

Evening Primrose oil (Oenothera biennis L.) is a rich source of Gamma linolenic acid (GLA) and other useful unsaturated fatty acids. Despite the diversity of sources of GLA, due to better absorption in the human body, evening primrose oil is the main source of GLA. In this study, the effects of pollination, harvesting method and application of salicylic acid on yield, yield components, and qual...
