Leaf contents of (A) proline (Pro), (B) glycine betaine (GB), and (C) total soluble sugars (TSS), in oleander seedlings after 15 and 30 days of (1) salt treatments with the indicated NaCl concentrations, and (2) complete withholding of watering. Bars represent means with SE (n = 5). Different letters above the bars (lowercase for 15 days and capital for 30 days treatments) indicate significant differences between salt or water stress treatments, according to Tukey’s test (α = 0.05).
