Conteúdo: | The cauliflower curd consisls of à main shool from which many firsl-order branches develop iii acropetal succession. Successive branching orders develop from lhe apices which exist on each branch and which forni lhe surface of lhe marketable curd. The branches have lhe sarne analomjcaj structure as lhe majority of herbaceous dicotyledons. Explants taken from the surface of lhe markelable curd of cauliflower were cultured, in nutrient medium. Starting on the fifth day after inoculation of the explant in the nutrient medium, the anatomical modifications in lhe explant were observed. The parenchymalic edis adjacenl lo lhe vascular bundles of lhe peduncle divide peridlinally and increase in volume. Apparently lhis phenomenon is related lo the differentiation of vascular elemenls which occur in a disorganized fashion. Concomitantly there is a progressive and gradual differentiation of the apical regions from undifferentiated meristems to organized shoot meristems, producing leaf primordia in a regular fashion. In approximatcly 10% of the cultures, bracts which were presenl on the explant developed greatly when in contacl with medium, and shools were formed from their biades.
