An attempt was made to elucidate a mechanism responsible for the resistance to 2,4-dichlorophenoxyacetic acid (2,4-D) of the meristematic cells in a 2,4-D resistant tobacco, Nicotiana tabacum cv. Samsun, callus (designated as S401) by investigating the basic differences in physiological features between the resistant callus and its sensitive parental callus (designated as S4). This paper will be focused on the differences in the contents of phenolic substances, peroxidase and polyphenoloxidase activities. Chlorogenic acid with a small amount of caffeic acid was a main polyphenolic substance in both the calli. The contents of the polyphenolic substances were at least 2 times as much in the sensitive callus, S4. Peroxidase and polyphenoloxidase, especially the latter, activities in the S401 were much less than those in the S4 callus. The S401 callus, unlike S4,responded to the removal of 2,4-D from the culture medium by increasing contents of the polyphenolic substamces and activities of the two enzymes as lignin content descrived previously.
