A: The phenotypes of control and transgenics treated with 0 , 150 and 200 mmol·L-1 NaCl for 2 days, Bar=5 cm; B:Plant height of control and transgenics treated with 0 and 150 mmol·L-1 NaCl for 3days; C: Root length of control and transgenics treated with 0 and 150 mmol·L-1 NaCl for 3days; D: Relative reduction of dry weight in the above-ground part of control and transgenics treated with 0 and 150 mmol·L-1 NaCl for 14 days; E: Relative reduction of dry weight in underground parts of control and transgenics treated with 0 and 150 mmol·L-1 NaCl for 14 days; F: Death rate of control and transgenics treated with 150 mmol·L-1 NaCl for 14 days; G: Dead leaf rate of control and transgenics treated with 150 mmol·L-1 NaCl for 14 days;* significantly different at P< 0.05 level (n = 3); ** significantly different at P< 0.01 level (n = 3). The same as below
