All values are mean±SD (n=3).
^a-cMeans with different superscripts in the same column are significantly different at p<0.05 by Duncan’s multiple range test.
^A-CMeans with different superscripts in the same row are significantly different at p<0.05 by Duncan’s multiple range test.
NS, not significant.
ND, not detected.
