Merck, C9157-2.5KG, Activated charcoal

Activated charcoal is originally used as an absorbent to remove toxic substances from plants. The use of activated charcoal in culture media gives it a dark colour. It induces absorption of phenolic, cell lysis products, ethylene, methane and many other compounds that are known to be deleterious to the plant tissue. Along with this, activated charcoal also absorbs growth regulators and other media components. In orchid, carrot and tomato tissue culture, activated charcoal induces growth and differentiation.
