Scanning electron microscopy (SEM) was used to study the monocarpic shoot development and florogenesis of three species from the genus Allium, in connection with their annual cycle. Initiation of leaf primordia in the Central Asian species, A. karataviense and A. altissimum, begins in the renewal bulb during the flowering stage of the mother plant. After differentiation of leaf primordia, the apical meristem of these species remains inactive for 6-10 weeks. The meristem begins florogenesis in August, during the 'dormancy' stage of the mother plant. In A. rothii from the Negev Desert, the apical meristem remains inactive for 12-15 weeks after flowering of the mother plant, leaf primofalls form in July-October and the meristem then becomes reproductive immediately. Since the inflorescences of all the species studied consist of regularly arranged cymes, many stages of floral development can be observed simultaneously.
