6-Benzylaminopurine has the dual functions of promoting buds and flowers

6-BA has the dual functions of promoting buds and flowers, and its specific effects depend on the application scenario and the growth stage of the plant. Its core mechanism is to break the apical dominance by regulating cell division and differentiation, and promote the growth of lateral buds and the formation of flower buds. ‌

The main mechanism of action of 6-Benzylaminopurine
‌1. Bud promotion ‌
6-BA promotes cell division and differentiation: induces dormant buds or non-differentiated tissues to develop into lateral buds, for example, applying dormant buds can stimulate the emergence of lateral branches.
6-BA breaks apical dominance: by regulating the ratio of auxin to cytokinin, inhibits the growth of the main stem apex and promotes the germination of lateral buds.

2. Flower promotion ‌
6-BA promotes flower bud differentiation: spraying during the flower bud differentiation period of fruit trees (such as peaches and citrus) can accelerate flower bud formation, increase flowering and fruit setting rate.
6-BA delays leaf senescence: by inhibiting chlorophyll degradation, maintaining the photosynthesis capacity of leaves, and providing sufficient nutrients for flower bud development.


Examples of 6-BA application scenarios
‌6-BA bud promotion‌: used for cutting propagation, to promote rooting of cuttings and lateral bud germination.
‌6-BA flower promotion‌: spraying during the flowering period of fruit trees (such as when peach trees are 80% flowering) can prevent flowers and fruits from falling and promote the development of flower buds into fruits.

Key regulatory factors of 6-BA
‌Concentration and timing‌: For example, spraying during the flowering period of citrus should be used in stages before physiological fruit drop to preserve fruits.
‌Plant species‌: It has significant effects on fruit trees such as peach trees, citrus, and grapes.
In summary, 6-BAP acts on the formation of buds and flower buds at the same time through cytokinin activity, and is an important tool for regulating plant growth balance in agricultural production.
