ABSTRACT

Histological and morphological analysis of growth apexes of broccoli (Brassica oleracea var italica, cv. ‘Fiesta’) was carried out to determine the time of its transition from a vegetative phase to a generative one, and particularly the time of initiation of inflorescence morphogenesis. Four developmental phases of the apex were distinguished and characterised: vegetative, evocation, early generative (initiation of inflorescence morphogenesis) and late generative. The changes taking place in apical and subapical meristem, as well as the configuration and size of the apex, its width and the sequences of appearance of generative structures, i.e. initials of first order floral stalks, were determined.

Key words: broccoli, curd initiation, temperature.
