Table 2 Immunofluorescence of S. europaea stem cross-section distribution and quantification of low and high methylesterified homogalacturonans (LM-HGs and HM-HGs) under NaCl stress for two populations (Ciechocinek and Inowrocław). Means and ± SD of replicates. Different letters indicate significant differences between treatments within population and * indicates significant difference between populations within treatment (p < 0.05), n = 5. The F values correspond to the 2-way ANOVA interaction of salt treatment × population.
