Stem applications of indole-3-acetic acid (IAA) or gibberellic acid (GA) did not prevent or alter tumor or teratoma formation in debudded tobacco plants (Nicotiana tabacum L., var. One Sucker). The materials produced intense (in case of GA) and moderate (in case of IAA) stem proliferations when applied to debudded plants but were without effect on intact plants.The results suggest that debudding-tumors are probably not related to or a result of an auxin or gibberellin deficit and that total debudding has a marked physiological effect on the plant. The altered physiological condition of the debudded plant, indicated by its responses to IAA and GA, may likely be related to tumor and teratoma formation.
