Research Abstract	Wetland plants usually suffer from oxygen deficiency in their belowground parts surrounded by reduced soils. They develop one or both of the two mechanisms, i.e., diffusion and convection, to supply oxygen from the air. Even for plants with convective gas transport, oxygen supply only by diffusion affords enough oxygen demand of roots. Oxygen supply by convection must play a role chiefly in runner elongation to enlarge their distribution.
