A method based on the measurement of ATP/ADP ratios is described. It permits the determination of the critical respiratory oxygen pressure of any organ, or part of any organ, of an intact plant. The data obtained by this method with intact maize (Zea mays L. INRA 508) root tips are compared with polarographic determinations on similar excised tissues.When internal O(2) transport from the aerial part was prevented, the critical oxygen pressure found for the respiration of intact tips was similar… CONTINUE READING
