6-Benzylaminopurine (6-BA) is a synthetic cytokinin-like plant growth regulator. In the field of leafy green preservation, 6-Benzylaminopurine is a synthetic cytokinin-like plant growth regulator with a molecular structure similar to natural cytokinins. It can mimic the physiological functions of endogenous hormones, influencing crop growth by regulating plant cell division and delaying senescence.
In leafy vegetables, it is often used as an anti-senescence and yield-increasing agent to improve yield and quality.
Mechanism of Action and Effects of 6-BA: 6-Benzylaminopurine (6-BA) mainly accelerates growth by activating the expression of plant cell division-related genes, promoting cell proliferation in meristematic tissues (such as root tips and shoot tips), increasing the number of organ cells.
Simultaneously, 6-BA can inhibit the activity of chlorophyll-degrading enzymes, delay leaf senescence, prolong photosynthetic time, and enhance the crop's resistance to adverse conditions such as drought and low temperatures. In leafy vegetables, this property helps maintain vibrant green leaves, reduces yellowing, and thus increases yield per unit area. For example, spraying can promote the transport of nutrients to leaves and economic organs, improving the color and fresh weight of leafy vegetables.
