^†

Mean values and the coefficient of variation (CV) are reported, along with the number of samples (n).

^‡

Differences among PGFs were tested using ANOVA with Duncan post hoc tests; different superscript letters (a and b) in each column indicate significant differences in the mean values at P<0.05.
