The growth and development of green flowering plants go through two different stages: vegetative growth and reproductive growth. The growth of vegetative organs such as roots, stems and leaves of green flowering plants is called vegetative growth. When green plants grow nutritionally for a certain period of time, they begin to form flower buds, then bloom, bear fruit and form seeds. The growth of reproductive organs such as flowers, fruits and seeds of plants is called reproductive growth. Generally speaking, vegetative growth is to grow bigger and better, and reproductive growth is to reproduce offspring. The two are interdependent and mutually restrictive. This contradictory and unified process promotes the growth and development of plants. Without strong vegetative organs, it is impossible to get enough nutrition for reproduction, and there is no material basis for the growth of reproductive organs. But if the vegetative organs grow too vigorously and consume too much nutrients, it will also inhibit the growth of reproductive organs. In nature, you can often see that many fruit trees grow extremely luxuriantly and often fail to bear fruit normally. Similarly, usually from the flower bud differentiation, the reproductive organs consume nutrients of the vegetative body, and the sugar obtained by the roots is reduced, which affects the absorption of minerals by the roots, and the aboveground parts are also affected. However, if reproductive growth is effectively restricted, vegetative organs such as branches and leaves can maintain robust growth.
