Rates of ROL along intact adventitious roots of rice grown under aerated or stagnant deoxygenated conditions. The experiment was conducted following the methods of Colmer et al. (1998) with minor modifications. Rice (cv. Nipponbare) was grown in a 28°C, continually lit growth chamber. Nine-day-old plants were grown in aerated nutrient solution (Aerated conditions) or stagnant deoxygenated agar solution (Stagnant conditions) for 14 or 15 days before measurements were taken along adventitious roots (80-130 mm long). ROL measurements were performed at 27-29°C under light conditions using cylindrical root-sleeving O₂ electrode. Values are means (n = 3) ± SD.
