6-Benzylaminopurine (6-BA) is a synthetic cytokinin-like plant growth regulator that regulates plant growth and development by mimicking the physiological functions of natural cytokinins. In tea cultivation, it is primarily used to promote bud formation and growth, thereby achieving bud-inducing and yield-increasing effects.
Mechanism of Action and Effects of 6-BA
6-Benzylaminopurine activates the expression of plant cell division-related genes, accelerating cell proliferation, especially strongly promoting meristematic tissues (such as root tips and shoot tips). In tea plants, it can break the dormancy of dormant buds, induce bud differentiation, promote lateral bud sprouting and new shoot growth, and increase the number of buds per unit area.
Simultaneously, this substance can inhibit chlorophyll decomposition, delay leaf senescence, prolong the photosynthetic time of functional leaves, and provide tea plants with more sufficient accumulation of photosynthetic products.
