The origin of Cotyledon and Epicotyl in Elettaria cardamomum Maton
Keyword(s):
A reinvestigation of embryo development in Elettaria cardamomum reveals that from the very early stages of development both the cotyledonary and epicotylary sectors are aligned adjacent to each other and are engendered by the derivatives of the terminal cell q. Thus the two sectors are topographically terminal on the proembryonal axis. One half of the working sphere is involved in the organization of the cotyledon and the other half in that of the epicotyl.
