Fig. 5From: Tolerance of citrus plants to the combination of high temperatures and drought is associated to the increase in transpiration modulated by a reduction in abscisic acid levelsEffect of the different stress treatments on metabolism and signaling of SA. CsPAL (a) and CsICS (b) relative expression, SA concentration (c) and CsPR2 (d) relative expression in Carrizo and Cleopatra plants subjected to drought (WS), heat (HS) and their combination (WS + HS). Different letters denote statistical significance at p ≤ 0.05. G: genotypes; T: stress treatment; GxT: interaction genotype x stress treatment. *P < 0.05; **P < 0.01; ***P < 0.001; ns: no statistical differencesBack to article page
