Data are represented as mean ± SE. ∗∗∗: significant at P < 0.001. For ANOVA analysis, within each row, means with different superscript (a, b, c, or d) are significantly different at P < 0.05, whereas means superscripts with the same letters mean that there is no significant difference at P < 0.05. LSD: least significant difference.
