The adenine nucleotide content of the 2-centimeter segments excised from tray-grown corn (Zea mays L., WF9 x Mo17) roots declines for the first hour after excision. Concomitant with the loss of adenine nucleotides is a decline in respiration and a leakage of K(+). With continued washing, these parameters partially or completely recover and increased phosphate influx develops. Increasing the wound effect by cutting 0.5-centimeter segments gives a more rapid and pronounced degradation of adenine nucleotides and slower recovery. Conversely, the mild injury caused by submerging intact roots induces less degradation and produces greater net adenine nucleotide synthesis during recovery; adding auxin to the washing medium produces a similar result. With all treatments, there is stabilization of energy charge at about 0.85.Brief submersion or rubbing of intact roots, as well as recutting washed and recovered root segments, will initiate the transient loss of adenine nucleotides but will not induce increased phosphate influx.It is suggested that the loss in adenine nucleotides may reflect homeostasis in energy charge via catabolism arising from membrane permeability changes.
