Abstract
Experiments conducted using Dioscorea alata L. revealed that an exudate from the cut end of the explants was responsible for browning of the culture medium. Browning did not affect growth of roots and shoots when explants were cultured in a large volume of medium, but in a small volume it was lethal. Sealing the cut ends with paraffin wax was found to control browning by preventing exudation. This simple technique permitted establishment of cultures in a small volume of medium in about 90 percent of the cases, while in unsealed cultures lethal browning was recorded in 80 percent of the cases. The advantages of this technique over other methods of controlling browning are discussed.
