^aMeans followed by different letters are significantly different, p ≤ 0.05, Duncan’s multiple range test.
^bBoldfaced data are significantly different from the control according to Dunnett’s t test.
^c, , , **, and ns indicate significance at p ≤ 0.05, 0.01, 0.001, 0.0001, and not significant, respectively.
