a
Significance of difference between results obtained with experimental treatments and the corresponding reference values was determined by t test (P < 0.05).
b
Significance of declining time trends was verified by one-way ANOVA (P < 0.05).
c
Exponential declining trend observed after excluding the data points at ≈22 h.
