POTASSIUM IODIDE

Potassium Iodide (KI) is used in plant tissue culture. It can:

• Reduce the induction phase in cultures
• Increase biomass and extracellular polymeric substances
• Inhibit the growth of some species
• Inhibit bacteria
• Promote the growth of shoots and callus

Explanation

• A study found that potassium iodide can reduce the induction phase in cultures of two diatoms.
• Potassium iodide can also promote the growth of shoots and callus in plant tissue culture.
