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.
