Table 1 Changes in the chlorophylls a, b, total, carotenoid and total soluble protein content in S. europaea populations (Inowrocław and Ciechocinek) under NaCl stress. 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 = 3. The F values correspond to the 2-way ANOVA interaction salt treatment × population.
