From: Peroxidase activity in scutella of maize in association with anatomical changes during germination and grain storage

Figure 7

Quantification of peroxidase activity in scutella of grains kept under controlled storage; germination and vigor assay. PODa is shown, with: a, catechin + H2O2, and b, guaiacol + H2O2 in extracts of scutella from maize grains that were stored up to 19 months. Activities were quantified after 24 h of imbibition; c, germination after 24 h of imbibition; correlation between germination and PODa, d-f quantified with catechin + H2O2, g-i quantified with guaiacol; j-l, vigor assays with MTT, which was applied to grains at end of storage time. Results are shown as means ± SD with up to 12 independent assays. ANOVA followed by a Tukey-Kramer Multiple-Comparison Tests were performed with p < 0.05. Symbols: data groups with different letters or numbers from the same storage conditions imply significant differences; and *, statistically significant differences comparing different treatments with same storage time.
