Abstract

Abstract Plant production was increased by treating ‘Centennial’ and ‘Julian’ sweetpotato roots with 250 to 1000 ppm GA or 1000 to 4000 ppm CEPA (2-chloroethylphosphonic acid). In general, GA treated plants were taller than controls and CEPA treated plants were shorter. Cutting roots into sections also increased plant production regardless of chemical treatment.
