| Abstract: | Exposure to gamma irratiation enhanced the cold tolerance of embryoid and callus in Omishima navel orange, and marked increase of the cell activity under lower temperature was shown. For embryoid and callus, the LT 50 were -4.8℃ and -5.9℃ respectively, 1.6℃ and 1.8℃ lower than those without irratiation respectively. At the same time, the content of soluble suga r , free proline, the activity of SOD and CAT were increased when treated by gamma irratiation. |
