Increased peroxidase activity and resistance to black rot was found in sweet potato roots incubated above infected roots in closed containers when compared with similar tissue incubated above uninfected roots. The peroxidase increases were detected in unpurified extracts and in extracts subjected to gel electrophoresis.
