6-Benzylaminopurine (6-BAP), benzyl adenine or BAP is a first-generation synthetic cytokinin that elicits plant growth and development responses, setting blossoms and stimulating fruit richness by stimulating cell division. It is an inhibitor of respiratory kinase in plants, and increases post-harvest life of green vegetables.

6-BA促进植物分枝，提高植物对病害、干旱、寒冷或高盐度的抵抗力，并通过减少花落来增加开花和果实座果率[1]。
