Zeatin is a plant hormone derived from the purinebase called adenine. Zeatin belongs to the family of plant-growth hormones called cytokinins and was discovered in immature corn kernels from the genus Zea. It promotes growth of lateral buds and when sprayed on meristems stimulates cell division to produce bushier plants.^{[citation needed]}

Zeatin and its derivatives are the active ingredient in coconut milk, which causes plant growth.^[1]

Zeatin has several anti-aging effects on human skin fibroblasts.^[2]

Toxicology

The acute transperitoneal toxicity in mice (LD₅₀) is 2200 mg/kg.

Application

Zeatin has a variety of effects including:

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.

Zeatin can also be applied to stimulate seed germination and seedling growth.
