Data are represented as mean ± SE. t-test values: : significant at . ANOVA analysis: within each row, means with different superscript (a, b, c, or d) are significantly different at , whereas means with the same superscript letters mean that there is no significant difference at . LSD: least significant difference; NS: nonsignificant.
