Transport can occur through aerenchymatous tissue via simple diffusion.
This study was conducted to elucidate the governing plant-mediated gas transport mechanisms in a midlatitude prairie wetland and to determine both their diel and seasonal variations and the importance of environmental controlling factors. Supporting measurements included solar radiation, air temperature, relative humidity, and windspeed. Pa during the day. At night culm pressures were at or slightly above atmospheric. No pressurization was detected in Scirpus.
