Fig. 1. The effect of increasing NaCl concentration on median germination time (T50) of Phaseolus species (averaged over all accessions). Data shown as mean ± standard error of the mean of four replicates, each replicate is the average of seven seeds. ANOVA indicated that median germination response was influenced by species at 0 mM (F = 70, P 0.0001), 60 mM (F = 44.1, P 0.0001), 120 mM (F = 18, P 0.0001), and 180 mM (F = 3.5, P 0.0179) NaCl concentration.
