On the Development of the Caryopsis
Year: 1893
Type: article
Abstract: I summarize my results and conclusions as follows: I.-In the corn, wheat and oat, at the time of fertilization, the single ovule is furnished with two integuments, which are more or less complete. As development proceeds (1) the outer integument soon disappears; (2) the inner cells of the ovary wall are absorbed in varying proportions; (3) the tissue of the nucellus is absorbed, with local exceptions. II.-At maturity, these remain as seed coverings: (1) the external portion of the ovary wall, in varying proportion, forming the pericarp; (2) the inner integument persisting in a state of compression. The epidermis of the nucellus also persists, though much compressed. III.-Late in the development of the fruit, the remaining (inner) integument becomes soldered to the adjacent inner cells of the pericarp forming the fruit correctly described by Mirbel under the name of "cerium," and rechristened by Richard the "caryopsis." This investigation was pursued in the botanical laboratory of the University of Wisconsin, under the direction of Prof. Charles R. Barnes. For his kind suggestions and help I wish to express my sincere gratitude.
