Abstract
Effects of a pulse of blue light on the extracellular pH in the pulvin us of Phaseolus vulgaris L. were studied with double-barreled pH-sensi tive microelectrodes. A blue-light pulse (30 s) induced transient alka lization, sometimes with initial acidification. This result is consist ent with the hypothesis that blue light inactivates the plasmalemma H-ATPase.
