Conteúdo: | The leaves of the pineapple originate acropetally as lateral projections of the apical growing region of the stem axis (figs. 21-23, 32). The initiating cells arise close to the apex of the stem from cells which are several cell generations removed from the initials in the main axis, as is the case in most plants (33). Both the surface layer of the meristem, the dermatogen, and the deeper, subdermatogen layers of cells are involved (fig. 23). The somewhta limited scope of these investigations permitted neither a detailed study of the exact layers of apical stem cells involved in the initiation of the leaf primordium nor a determination of the specificity of the initial cell layers of the young leaf whith respect to the tissues ultimately derived from them , such as several workers have done for various plants in recent years (18, 27, 28, 43, 44, 60). Initiation of a leaf primordium is first evidened by the apparently more rapid division of cells in both the surface layer and several-usually two or three-layers beneath this, in a region delimited as described below.
