A 50 cm-wide and 3 m-long belt transect situated in a Zizania latifolia zone across the strand of Lake Hinuma was divided into six plots ranging from a dry to a water-logged conditions. In plot V, just below the lowest summer water level, the rhizomes had the least dry matter per quadrat and most, of them were very short, resulting in a maximum shoot/rhizome ratio. The ventilation coefficient and oxygen concentration inside the basal stem were measured and oxygen flux was calculated. The values for the oxygen concentration inside the basal stem correlated well with the soil surface (1 cm deep) redox potential and showed the minimum at plot V, where the development of rhizome was worst. It was surmised that the intensely lowered redox potential of soil at plot V has caused the loss of oxygen through the underground organs. Although the caculated flux at plot V was maximum among the plots, low concentration at the rhizome tip would have suppressed the elongation of rhizome, causing more dry matter to be distributed to the aerial shoots.
