NEED OF COLD TO APPLE SEED GERMINATION |
| Authors: | C. Thévenot, D. Côme |
| Abstract:
Apple embryos as those of many Rosaceae are often dormant at the time of harvest. Several weeks treatment at low temperatures (0–4°C) is necessary to give them the capability of germination. Even after a cold treatment non-dormant embryos germinate better at cool temperatures (15–20°C) than at 25 or 30°C. Furthermore a coat inhibition was demonstrated in apple seed germination. Because of such inhibition seed germination needs cool temperatures. This need of cold to breaking of embryo dormancy, germination of non-dormant embryo and seed germination shows that temperature plays an important role in apple seed germination. | |
