2.4. Statistical analysis
The measurements of enzymes were analyzed by a twofactor
completely randomized ANOVA, which compared the
flooding treatments and the entries. For the significant values,
means were separated by the least significant difference
(LSD) test at P ≤ 0.05, 0.01 or 0.001, using PC SAS 6.12
(SAS Institute, Cary, NC). The results are presented in the
tables and figures.
