Abstract
During expts. with synthetic plant hormones on potatoes an increase in the red skin color of the variety Bliss Triumph was noted. Na and NH4 salts and the butyl ester of 2, 4-D were applied to the soil as a side dressing when tubers were one-third grown. Rates of 20, 200, and 400 lb. /acre of the acid equivalents were used. No injury to the plants or reduction in yield was seen with the 20 lb. / acre, but these effects occurred when 200 and 400 lb. /acre were applied. All rates showed an increase in the red skin color of Bliss Triumph tubers grown in sandy soil. No change in flesh color or flavor of the treated tubers was noted.
