What is TDZ hormone?
What is TDZ hormone?
It is a family of phytohormones essential for the development of the plant as well as auxin, which acts as hormones in plants. Thidiazuron (TDZ) is used in tissue culture and can promote or accelerate the organogenesis and plant regeneration.
Is TDZ a cytokinin?
Thidizuron (TDZ) is among the most active cytokinin-like substances for woody plant tissue culture. It facilitates efficient micropropagation of many recalcitrant woody species. Low concentrations (<1 µM) can induce greater axillary proliferation than many other cytokinins; however, TDZ may inhibit shoot elongation.
Is Thidiazuron a herbicide?
Thidiazuron can also be used as a herbicide, because an appropriate dose and timing of administration completely stops growth. The product was marketed by Aventis CropScience; later merged into Bayer CropScience. Brand names are Dropp (for use in the cultivation of cotton) or Revent (for use in fruit production).
How do you dissolve Thidiazuron?
Thidiazuron is soluble in organic solvents such as ethanol, DMSO, and dimethyl formamide (DMF), which should be purged with an inert gas. The solubility of thidiazuron in these solvents is approximately 1, 15, and 30 mg/ml, respectively.
Is TDZ autoclavable?
Yes hormones like NAA, BAP, 2,4-D are autoclavable. But filter sterilization is needed for some hormones like IAA, TDZ, GA. Synthetic plant hormones such as NAA, 2,4 D, BAP are autoclavable but natural plant hormones for example zeatin, kinetin are heat labile.
How do you make a TDZ stock solution?
Dissolve TDZ in 2-3 ml of either KOH or NaOH. Then make final volume by adding glass distilled water. To make 10 ml of 1mg/ml TDZ solution, I dissolved 10 mg (0.02 g) of TDZ in 1ml of 1N NaOH, then adjusted to 10ml with distilled water. TDZ I always disolve in small volume of 1N KOH.

Is ethephon a hormone?
Ethephon is a systemic plant growth regulator belonging to the phosphonate family. It is readily absorbed by the plant and releases ethylene which is a natural plant hormone.
How do I add auxin to my plant?
Auxin-based rooting hormones may be mixed with talc and applied to the base of cuttings. The cuttings are dipped in the powder, then lightly tapped to remove excess chemical. To increase adhesion of powder to cutting bases, stem tissue can be re-cut or dipped in water or alcohol before application.
