ABSTRACT
Activated carbon plays an important role as a medium supplement and will be discussed shortly. The literature applications of activated carbon in tissue culture species include carrot, plum, banana, guava, raspberry, strawberry, grape, apple, pineapple, sweet potato, potato, cabbage, cucumber, lettuce, cauliflower, artichoke, mango, melon, oil palm, tobacco, sweet orange, and tea. As a recommendation, a tailored carbon-hydrocolloid blended product would penetrate a significant market in plant cell tissue culture users if it was scientifically validated by a reputable laboratory and properly marketed to the scientific community. Activated charcoal treatment studies with lavandin and Anemone seedlings in tissue culture showed that the positive effects of carbon treatments cannot be related to ethylene adsorption but probably to the removal of unidentified inhibitory substances from the culture medium. Some experiments with geranium showed blossoms in a rootless culture only with carbon present.
