Plant process by which the shoot apical meristem changes its anatomy to generate a
floweror inflorescencein lieu of new nodes with leaves. Anatomical changes begin at the edge of the meristem, generating first the outer whorls of the flower- the calyx and the corolla, and later the androeciumand gynoecium.
Flower differentiation can take from only a few days (in
annual plants) to 4-11 months (in fruit crops).
