A model has been developed that relates the stages of spring bud development of 'Redhaven' and 'Elberta' peaches (Prunus persica (L) Batsch) to an accumulation of growing degree hours following rest completion. The accumulation of growing degree hours is based on a lower limit of 4.5°C and an upper limit of 25°.
