Fig. 6From: 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 levelsABA, ABAGE, PA and DPA levels in citrus plants subjected to different stress treatments. ABA (a), ABAGE (c), PA (b) and DPA (d) levels 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
