In comparison to the control conditions, the negative values represented decreasing percentages of the investigated parameters. Letters in the same row with different meanings specify statistically significant differences (p ≤ 0.01) using Duncan’s new multiple range test. The values are presented by the trait index (%) ± standard error. The values shown are the averages of eight separate measurements.
