The postanaerobic behavior of sweet potato roots from a flood-tolerant cultivar, 'Centennial,' and a flood-susceptible cultivar, 'Caromex,' was studied. High concentrations of CO2 and low concentrations of O2 were present in the internal atmosphere of 'Caromex' roots even after the anaerobically pretreated roots were restored to air for a few days, whereas in 'Centennial,' the internal gas atmosphere was less affected by anoxia. Ethanol accumulation in 'Caromex' was consistently higher than in 'Centennial,' and the postanaerobic changes were different between cultivars. An inducation of electrolyte leakage was observed from both cultivars immediately after roots were exposed to a CO2-enriched environment for 48 h. The leakage became greater in 'Caromex' after a 3-day aerobic exposure. In 'Centennial,' leakage of electrolytes due to CO2 treatment diminished at the end of 3 days. Application of ethanol to the discs had no immediate effect on electrolyte leakage in either cultivar under a N2 environment. However, anaerobiosis alone resulted in higher electrolyte leakage. It remains to be determined that the postanaerobic patterns of 'Caromex' and 'Centennial' are characteristic of flood-susceptible and flood-tolerant sweet potato cultivars in general.

ABSTRACT Enzyme assays are based on methodologies described in the literature. However, the enzyme kinetics must be adjusted to obtain more reliable results. This study aimed to adjust assays by testing different polyphenol oxidase (PPO) and peroxidase (POD) extract amounts and reaction times in sweet potato cultivars harvested at different times. Sweet potato cultivars Paraná, Mãe de Família, and ESAM1 were harvested at 120, 150, and 180 days after planting and minimally processed. A 0.25 g sample was used to determine PPO and POD activities immediately after minimal processing at each harvest. Extraction was performed in 1500 μL phosphate buffer (0.2 M, pH 6.0). The PPO assay was performed by adding 10-50 μL extract, 1490-1450 μL phosphate buffer (0.2 M, pH 6.0), and 1500 μL catechol (0.2 M). The POD assay was carried out by adding 10-50 μL extract to a reaction medium containing 1790-1750 μL phosphate buffer (0.2 M, pH 6), 100 μl guaiacol (5 g L-1), and 100 μL hydrogen peroxide (0.8 g L-1). In both cases, the evaluated reaction times were 1, 2, and 3 min. In the three cultivars, PPO and POD activities increased with the volume of extract and reaction time at all harvest times. The enzyme extract volume of 10 μL for 2 min promoted a continuous increase in PPO and POD enzyme activities in all studied cultivars and at all reaction times.
