The relationship between vegetative organs and reproductive organs is also interdependent and mutually restrictive. Vegetative growth is the basis of reproductive growth. Only the healthy growth of roots, stems, leaves and other organs can create good conditions for the formation and development of flowers, fruits and seeds. The good development of fruits and seeds laid a material foundation for the growth of a new generation of vegetative organs. The mutual restriction between vegetative organs and reproductive organs is also manifested in the competition for nutrients. If the growth of vegetative organs consumes too much nutrients and the vegetative growth is too vigorous, it will lead to delayed reproductive growth or stunted reproductive organs. As a result, cereal crops are greedy for green leaves and mature late, and cotton and fruit trees drop flowers and fruits. However, if too much nutrients are consumed in the growth of reproductive organs, reproductive growth will be too vigorous, which will also affect the growth potential and growth of vegetative organs, and even lead to premature aging and death of plants.

It is of great significance in production to reasonably adjust the relationship between them so that the growth of vegetative organs and reproductive organs can develop harmoniously and purposefully. Plants (such as tea, mulberry, hemp, leafy vegetables, etc.) that harvest vegetative organs can obtain high yield if sufficient water and fertilizer are provided, flowers or buds are picked, or appropriate pruning is carried out; For example, in cotton production, measures such as pruning, topping and removing redundant buds can be taken to control the growth of vegetative organs and ensure the growth of cotton bolls and peaches. Using their relationship skillfully in fruit tree production can eliminate the phenomenon of "big and small years" and obtain high yield every year.
