Abstract
The embryogeny ofCommelina benghalensis L, from zygote to the globular proembryo, is presented. The terminal cell of the proembryo, after two vertical divisions, right angles to each other, becomes morphogenetically differentiated: one of the half-hemispheres is destined to develop into the cotyledon and the other into the epicotyl. The subjacent tier—derivatives of the basal cell—which is close to the terminal tier, show two ontogenetic norms of development. The root pole is differentiated from the derivatives of the basal cell which are opposite to the shoot pole.
The general outline of the proembryo as a whole becomes globular without any external morphological recognition into the cotyledon and epicotyl at the shoot pole. Nevertheless, the cotyledonary and epicotylary sectors of the terminal hemisphere lying adjacent to one another and occupying a truly terminal position on the embryonal axis, a position opposite to the root pole, can be recognised.
