6-Benzylaminopurine (6-BA) effectively stimulates the sprouting of lateral buds in crops. It is a cytokinin-type plant growth regulator that promotes lateral bud growth by breaking apical dominance.
The mechanism of action of 6-Benzylaminopurine mainly involves regulating the hormonal balance within the plant and activating cell division activity in meristematic tissues, thereby guiding lateral buds to break dormancy.
In practical applications, the treatment method varies depending on the crop and growth stage: For flowers such as roses, incisions can be made 0.5 cm above and below the axillary buds in spring and autumn, and a 0.5% 6-BA paste can be applied. In the shaping of young apple trees, a 3% liquid solution diluted 75–100 times can be sprayed during the vigorous growth period to stimulate the sprouting of lateral buds and the formation of lateral branches.
During the vigorous growth period of summer shoots, the concentration of 6-BA, the apple variety, and the node position will affect the effect, and the substance can only be transported within the plant to a limited extent (generally 2.5–5.0 cm, with a maximum distance of 12 cm). When using this product, pay close attention to concentration control to avoid excessive dosage, which can lead to deformities or abnormal growth.
