Flower bud differentiation is an important turning point from vegetative growth to reproductive growth and an important stage of plant development. In the process of flower bud differentiation, the vegetative cells of plants will change to form flower bud cells, which will form flower buds, thus making plants enter the stage of reproductive growth and the beginning of plant reproduction.

Vegetative growth means that the roots of plants grow from the radicle of seeds. When seeds germinate, meristem cells of radicle divide and grow, which makes roots grow continuously, and the elongation zone of roots grows fastest.
