| Summary, etc. |
Nitrogen fixation by bacteria associated with roots of intact maize plants was measured by exposing the roots to 15N2 at a partial O2 pressure (pO2) of 2 or 10 kPa. The plants were grown in a mixture of Weswood soil and sand and then transferred to plastic cylinders containing an N-free plant nutrient solution. The solution was sparged continuously with a mixture of air and N2 at a pO2 of 2 or 10 kPa. Acetylene reduction was measured after the roots were exposed to the low pO2 overnight. The air-N2 atmosphere in the cylinders was then replaced with an O2-He atmosphere at the same pO2, and the roots were exposed to 20 kPa of 15N2 for 20 to 22 h. |
