Mass flow of air to the submerged parts of the plant constitutes the major mechanism of aeration in partially submerged rice. It is proposed that the flow of air results from reduction of pressure in the air-conducting system of the plant caused by consumption of oxygen and solubilization of respiratory carbon dioxide in the surrounding water.
