S ummary A faster than normal rate of leaf production in the rogue tomato leads to earlier flowering in summer. In winter, growth of the inflorescence is less than the normal, often resulting in abortion. In the rogue there is an early short‐term stimulation of growth of all axillary buds. This, together with a smaller leaf area and shorter internodes, creates the characteristic rogue appearance. In general, however, the pattern of axillary growth along the stem is similar in rogue and normal plants; an observation which provides little support for the theory that the rogue appearance is due to loss of apical dominance. Neither removal of the first two leaves nor IAA application influences the rate of leaf initiation in the rogue as it does in the normal, indicating the possibility that the rogue has a modified auxin control system.
