Seasonal changes in flower development in peach. Dormant buds (on the left) require a period of chilling to become competent for growing (on the middle). After dormancy, microsporogenesis is initiated, followed by flower opening after a period of warm temperatures (on the right). A single vegetative bud (VB) is typically flanked by two flower buds (FB).
