Standard error of the means.

Group × Time.

Different letters on the same line show statistical differences during time in the same group: A, B = p < 0.01; a, b = p < 0.05; Different letters on the same row show statistical differences between groups at the same aging time: X, Y = p < 0.01; x, y = p < 0.05.
