This study aimed to investigate the role of ascorbate peroxidase (APX), guaiacol peroxidase (GPX),
polysaccharides, and protein contents associated with the early events of postharvest physiological
deterioration (PPD) in cassava roots. Increases in APX and GPX activity, as well as total protein contents
occurred from 3 to 5 days of storage and were correlated with the delay of PPD. Cassava samples stained
with Periodic Acid-Schiff (PAS) highlighted the presence of starch and cellulose. Degradation of starch
granules during PPD was also detected. Slight metachromatic reaction with toluidine blue is indicative
of increasing of acidic polysaccharides and may play an important role in PPD delay. Principal component
analysis (PCA) classified samples according to their levels of enzymatic activity based on the decision tree
model which showed GPX and total protein amounts to be correlated with PPD. The Oriental (ORI)
cultivar was more susceptible to PPD. |
