Time course of the cis-piceid accumulation in: Razegui control (RazeguiC), Razegui stressed (RazeguiS), Syrah control (SyrahC) and Syrah stressed (SyrahS). Evaluation was carried out in leaf samples of plants exposed to a 24 h salt stress treatment (NaCl at 100 mM) in controlled conditions of hydroponic culture, followed by a 24 h recovery phase. Data represent mean values and standard errors of 3 independent experiments. Letter suffixes express significant differences between the values among the salt stress treatments at p < 0.05 according to Duncan’s multiple range test. No significant difference has been shown between cis-piceid values among the control leaves
