Hormonal profiling of leaf samples of Quantis.™-treated and untreated (water-control) potato (cv. Maris Piper) collected at 24 h post-application (following heat stress for 12 h) and 7 days post-application. a Gibberellin A4 (GA4), b trans-zeatin (Z), c abscisic acid (ABA), d auxin (IAA), e salicylic acid (SA), f jasmonic acid (JA) Concentrations of endogenous phytohormones were determined by liquid chromatography coupled to electrospray ionisation tandem mass spectrometry (LC/ESI–MS/MS). Data represent mean ± SEM of seven biological replicates per treatment. Asterisk indicates significant difference according to Student’s t test, p < 0.05
