(1) The Structure of root Cap}, JOURNAL = {Taiwania}, VOLUME = {36}, YEAR = {1991}, ISSUE = {3}, PAGES = {235-247}, URL = {https://taiwania.ntu.edu.tw/abstract/159}, ABSTRACT = {numerous thin, adventitious aerial roots develop on the stems of Ficus microcarpa L.f.. They bear root caps, but lack root hairs. In this paper, the tips of aerial roots of Ficus microparpa were investigated by means of light microscopy, scanning electron microscopy and transmission electron microscopy. In the median longitudinal section, the culumella consists of 8-15 layers of living parenchyma cells derived from the calyprogen. The peripherial cells of the root cap are callapsed and sloughed off. The cells of calyprogen have a large nucleus with a pronounced nucleolus and many small vacuoles. The plastids are proplastids.when the cells of the cap leave the initial zone, the alteration in the ultrastructure of plastids including the build-up and the break down of starch grains, mitochondria and endoplasmic reticulum can be recognized. The culumella cells (statocytes) of aerial root cap in Ficus microcarpa show no strict ultrastructural polarity.}, DOI = {10.6165/tai.1991.36.235} }
