Summary
White Rose potato tubers, scrubbed through a series of 24, 48, or 72 brushes, were exposed to fluorescent light for various periods of time. Scrubbed tubers contained more chlorophyll. Tubers under burlap were less green than those exposed to full light. Those under 10-oz. burlap showed less greening than those under 7 1/2-oz. burlap. Waxing the tubers had no effect on chlorophyll formation.
Ways to reduce chlorophyll development in potatoes are suggested.
