Figure 2: Effects of increasing NaCl levels on relative growth rate (RGR) (a), unit leaf rate (ULR) (b), leaf area ratio (LAR) (c), and specific leaf area (SLA) (d) for Phaseolus species, based on the differences between two means (10–15 and 15–20 days). Each value represents the mean ± SE of six replicates. Control (filled symbols) and salt treatments open (symbols).
