Zeatin is a powerful plant growth regulator that promotes callus initiation when used with auxin, enhances fruit set, and retards yellowing in vegetables. It's also effective in stimulating seed germination and seedling growth.
Specifically for tomatoes, spraying 8ppm three times during the blossom, flowering period, and after flowering can increase yield by 6.59% to 18.75% and enhance vitamin content. For blueberries, spraying 8ppm three times during the rosette stage can increase yield by 7.13% to 16.19% and improve fruit quality.
