Rates of radial oxygen loss (ROL) along adventitious roots in accessions of O. glumaepatula, O. rufipogon, and rice (cv. Nipponbare) under aerated or stagnant conditions. W2165 (a), W2149 (b), and W1183 (c) of O. glumaepatula came from wetlands. W1962 (d) of O. rufipogon came from habitats other than wetlands. For a control that forms an inducible ROL barrier, cv. Nipponbare (e) was used. ROL along adventitious roots (115–120 mm length) was measured by Pt cylindrical electrode. Plants were grown in aerated nutrient solution for eight days and then transferred to deoxygenated stagnant 0.1% agar solution or continued aerated solution for 13–15 days. Mean ± standard error (SE). n = 3 or 4.
