Physiology of flowering in apple and almond: A review

Flower bud formation is a intricate phenomenon. Numerous studies on flower bud formation of temperate fruit plants have been conducted in many .In spite of that, a great part of the most important characteristics of flower bud formation remains insufficiently clarified both by theoretical biology and applied horticulture. Special attention deserves the clarification of the morphogenetic changes that occur between the vegetative state of the buds and the initiation of flower organs. Flowering takes place by the transformation of vegetative apex into a reproductive structure under the control of endogenous and exogenous elements. When the apex of the vegetative bud receives a signal for differentiating as a flower bud, a sequence of events takes place.
