The data represent mean ± standard error (SE) and the values is an average of recordings from three independent experiments, each with three replicates (i.e. n = 9). Different alphabetical letters indicate statistically significant differences at p ≤ 0.05. Values followed by the same letter in a column indicate no significant difference between treatments following Tukey’s studentized range (HSD) test
