The objectives of this study were
to investigate the antifungal activity of chitosan against
S. sclerotiorum in vitro and in carrot, and its possible mode
of action by evaluating plasma membrane integrity, protein
leakage and lipid peroxidation in S. sclerotiorum and the
elicitation of defense enzymes, including polyphenoloxidase
(PPO) and peroxidase (POD) in carrot by chitosan.
