Ultrastructural Study of the Shoot Apex in Sorghum Bicolor
Abstract
Considerable research has been published on the structure and function of the apical meristem of the shoot. Many review a rtic le s on this subject have appeared from time to time (Bernier, 1965; Cutter, 1965; G ifford, 1954, 1971; Nougarede, 1967; Romberger, 1963; and Wardlaw, 1965). The reason for this in te re st is that this meristematic region plays an important morphogenetic role during the ontogeny o f the vegetative plant body in such processes as phyllotaxis, degree of b ran c h in g ,tillerin g , and shoot form. Under certain conditions, a dramatic and exciting change occurs in the lif e of a higher plant when this meristem terminates its vegetative role and transforms into a flo ra l apex. A fter a series of developmental sequences a flower or an inflorescence w ill be formed. Thus, the shoot apex offers a good system fo r studying the fundamental problems of histogenesis and organogenesis in relation to its regulating factors. On the other hand, an understanding of its organization and a c tiv ity is essential in agricultural and horticultural practice.
