Gas emission rates from the submerged soil surface in Zizania latifolia-planted pots were higher than those from unvegetated pots and increased with increasing biomass. The oxygen supply from the atmosphere through the plants to the soil had presumably activated nitrate production by nitrification in oxic soils, and the nitrate had accelerated denitrification in adjacent anoxic soils. In contrast to the results for Z. latifolia, gas emission rates from soil in Phragmites australis-planted pots were lower than those from unvegetated pots. Gas generated in soils could be carried to the atmosphere through the ventilation pathway in the plant body rather than through the soil by diffusion and via the overlying water as air bubbles.
