Root growth of cress seedlings in dependence with alaying time and b HMP dose. a One point represents the average root length for the dose-variant Control measured in 160 bags from 8 trials (in mm). Error bars represent ± standard error. Treatments at a time point with no letters in common differ significantly by a Tukey–Kramer test (p < 0.0001). b One point represents the difference of average root length of D1µl or D0.1µl relative to average root length of Control at constant laying time (in %, relative to control). Error bars represent ± the standard error of a difference. For each time point, asterisks indicate significant differences as determined by a Tukey–Kramer test: *(0.01 < p < 0.05), **(0.001 < p < 0.01) and ***(p < 0.001)
