Effects of pH and Ethephon on Betacyanin Leakage from Beet Root Discs

Michael S. Reid, Jack L. Paul and Roy E. Young1

Department of Environmental Horticulture, University of California, Davis, California 95616

Betacyanin leakage from beet root discs was found to increase with decreasing pH of the incubation medium. Although 10 millimolar Ca2+ reduced pigment leakage at pH 3.5, it was ineffective at pH 2.3. Leakage was also stimulated by 100 micrograms per milliliter (2-chloroethyl)-phosphonic acid (pH 3.1), but when the solution was neutralized, this leakage was eliminated. Bubbling C2H4 through a neutral medium containing beet discs had no effect on pigment leakage; it appears that the effect of Ethephon solutions on this process is a function of their low pH.
