Changes of ion leakage with water stress time. Ion leakages in leaves were measured at each day from 0 to 6 days after treatment with PEG (PEG) and without PEG (CK). Values are means ± SE (n = 3). One asterisk (*) and two asterisks (**) represent significant differences between PEG and CK at P < 0.05 and P < 0.01 respectively
