Abstract

By Roy M. SACHS3 Department of Landscape Horticulture, University of California, Davis, California Dwarfism, whether owing to genetical, environmental, chemical, or root­ stock factors, and the transition from long-shoot to short-shoot or from rosette to caulescent growth habit are special cases of stem elongation. Many problems of form are concerned in part with the genesis of the plant's long axis, yet with the exception of Romberger's recent review ( 133) , stem elonga­ tion is rarely discussed in books or monographs on morphogenesis (3, 147). In fact, the subject is usually alluded to only in reviews on the physiology of growth substances. There is, however, a wealth of information concerning stem elongation, per sei indeed, there is not sufficient space here to present a complete review of this subject which encompasses all factors affecting plant height. For organizational purposes, the text has been divided into two cate­ gories, Anatomy and Physiology, in which there is considerable overlap. Recent research on stem elongation reflects the value of a dual, physiological­ anatomical approach, and it is desirable that this integrated view should also prevail in new textbooks.
