Figure 9. Comparison of cold and freezing tolerance between transgenic T2 plants derived from Line 28 (left tray) and wild-type (right tray) plants: (A, B, and C) plants after exposure to 4, 0, and –2°C, respectively, for 48 h; (D, E, and F) after a 2-wk recovery period under greenhouse conditions (26°C). (G) Electrolyte leakage of transgenic and control plants that were grown at 26°C and were then exposed to 0, 4, and –2°C for 48 h; and (H) comparison of survival rates after cold and freezing treatments of transgenic and wild-type plants after 2 wk of recovery from 0, 4, and –2°C exposure for 48 h.
