SEF, spectral edge frequency. n.s. means that the effect is not significant. *P < 0.05; **P < 0.01. †The data are the F‐values calculated in the analysis of variance. Blank entries indicate that the corresponding effect was not applicable to that variable. Effects of all the two‐factor interactions are reported.
