Bud differentiation refers to the process of that axis growing point is changed into inflorescence or flower by mitogenetic blade, axillary bud out.Bud
Differentiation is the physiology and morphological landmarks changed from nutrient growth to reproductive growth.General bud differentiation can be divided into Physiological Differentiation, shape
State breaks up two stages.The process that growing point converts in physiological status to bud in bud, referred to as Physiological Differentiation.Bud physiology point
Change state when completing, referred to as flower originator.Hereafter, just start the morphing process of flower bud development, referred to as Morphological Differentiation.
The morning and evening of physiological flower bud differentiation phase and tree species, kind, tree vigo(u)r, stock, branch type and bud position locating on branch
It is equipped with pass.
Physiological flower bud differentiation phase is to determine whether leaf bud can be changed into bud, determines the pass for developing into female flower or male flower
Key.The formation of bud depends on the related information transmitting with " DNA --- RNA --- protein ", is in certain dependent on leaf bud
