In the same row, values with no letter or the same letter superscripts indicate no significant difference (P > 0.05), while values with different small letter superscripts indicate significant difference (P < 0.05), and values with different capital superscripts indicate significant difference (P < 0.01). ANOVA, analysis of variance; SEM, standard error of the mean.
