Abstract

The wetcork containing more than 400% moisture is developed as islets in the otherwise dry cork tissue of Quercus suber. A characterization using electron moscroscopy yielded no marked differences in the wall structure, except for formation of gaps due to lack of substances in the middle lamella of some wetcork cells. The chemical constitution of the two tissues types equally showed no obvious differences. During drying the wetcork shrinks to a great extent, thus influencing the utilization of such a cork in certain fields of application.
