Zeatin FAQ Section 1
What is the recommended concentration for Zeatin in plant tissue culture?
The recommended concentration of Zeatin for most plant tissue culture applications ranges between 0.1-10 mg/L. For shoot induction, a typical concentration is 0.5-2.0 mg/L, while for shoot multiplication, 0.1-1.0 mg/L is commonly used. However, optimal concentrations may vary depending on the plant species and specific application requirements.
How does Zeatin differ from other cytokinins?
Zeatin is considered one of the most active natural cytokinins. Compared to other cytokinins like kinetin or benzyladenine (BA), Zeatin often shows stronger activity at lower concentrations and typically induces better-quality shoots with less callus formation. It's particularly effective for difficult-to-culture plant species where other cytokinins might fail to produce satisfactory results.

Zeatin FAQ Section 2
Can Zeatin be used in combination with other plant growth regulators?
Yes, Zeatin is often used in combination with auxins like IAA or NAA to achieve balanced growth in tissue culture. The typical ratio is higher cytokinin (Zeatin) to auxin for shoot proliferation (e.g., 2:1), and lower cytokinin to auxin for root formation (e.g., 1:2). The exact combination and ratio depend on the plant species and desired outcomes.
How should Zeatin solutions be prepared and stored?
Zeatin stock solutions are typically prepared at 1 mg/mL concentration using a small amount of 1N NaOH to aid dissolution, followed by dilution with distilled water. For long-term storage, aliquot the solution and keep at -20°C. Avoid repeated freeze-thaw cycles as they may degrade the compound. Working solutions should be prepared fresh when possible.

Zeatin FAQ Section 3
What are the signs of Zeatin degradation?
Degraded Zeatin may show color changes from white/off-white to yellow or brown. The powder may become clumpy or show reduced solubility. In solution, precipitation or cloudiness may appear. Biological activity tests showing reduced efficacy also indicate potential degradation. Always store Zeatin properly and check expiration dates before use.
Is Zeatin suitable for organic farming?
Natural Zeatin derived from plant sources may be suitable for certain organic farming applications, but regulations vary by country and certifying agency. Synthetic Zeatin is generally not approved for organic farming. Always check with your local organic certification body for specific guidelines regarding cytokinin use in organic production systems.
