Notwithstanding its reported effect upon the levels of native auxin in plant tissues, 2, 3, 5-triiodobenzoic acid (TIBA) does not influence sex expression in Cannabis sativa, a dioecious species in which there is evidence that flower sexuality may be regulated by auxin levels in the neighbourhood of developing primordia. The total production of flowers is, however, increased in both sexes by TIBA, an effect possibly resulting from an alleviation of the correlative inhibition of lateral buds. Whilst hardly influencing morphogenetic activity at a cellular level at all, TIBA treatment leads to gross ontogenetic abnormalities, of which the common feature is a tendency for the elimination of localized growth and the substitution instead of generalized growth fields, resulting in the formation of infundibuliform and cylindrical foliar and floral structures. It seems probable that the bulk of the effects of TIBA in the plant may be due to an influence on auxin distribution, perhaps through interference with the mechanism of polar transport.
