We characterize the growth form of the two types of commercial tomato cultivars. In both types of tomato the branching is sympodial. The difference between cultivars of the indeterminate and the determined type is given by variations in the intensity in which the spatial and temporal pattern of the sympodial growth is expressed. Variations that manifests itself in the relative rate of development of each sympodial unit and in the amount of sympodial shoots that are produced during the plant's lifetime. The inflorescences of tomato plants grown in greenhouse are studied. The main inflorescences variations that have been observed are: the appearance of either dichasial inflorescences or pleiochasial inflorescences; the bracts development at the level of either the branches of the inflorescence or individual flowers; and the proliferation of the apex of the inflorescence.
