ENVIRONMENTAL FATE
No data available.
Usage: Zeatin is a plant hormone derived from the purine adenine. It is a member of the plant growth hormone family known as cytokinins. Zeatin was first discovered in immature corn kernels from the genus Zea. It promotes growth of lateral buds and stimulates cell division to produce bushier plants if sprayed on meristems.
Application:
1. Promotes callus initiation when combined with auxin, concentration 1 ppm.
2. Promotes fruit set. Zeatin 100 ppm + GA3 500 ppm + NAA 20 ppm, sprayed at 10th, 25th, 40th day after blossom.
3. Retards yellowing for vegetables, 20 ppm, sprayed.
4. Causes auxiliary stems to grow and flower.
It can also be applied to stimulate seed germination and seedling growth.
