Data are represented as mean ± SE. T-test values ***: significant at P < 0.001. 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
