Effects of 10–30% PEG treatments on the leaf water potential, osmotic potential, and turgor pressure of sweet sorghum.

PEG Concentrations	Water Potential (Ψw, MPa)	Osmotic Potential (Ψs, MPa)	Turgor Pressure (Ψt, MPa)
0	−0.20 ± 0.01 a	−0.64 ± 0.02 a	0.44 ± 0.02 a
10%	−0.52 ± 0.02 b	−0.90 ± 0.04 b	0.38 ± 0.02 a
20%	−0.67 ± 0.02 c	−0.98 ± 0.03 c	0.31 ± 0.02 b
30%	−1.17 ± 0.05 d	−1.36 ± 0.04 d	0.19 ± 0.01 c

Data are means (±SDs), n = 6. Different letters indicate significant differences determined by Tukey’s HSD test (p < 0.05).
