Root growth of cress seedlings with dependence on alight and b HMP dose. a One point represents the average root length for the dose-variant Control measured in 120 bags from 6 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 < 0.05). b One point represents the difference of average root length of D1µl relative to average root length of Control at constant light (in %, relative to control). Error bars represent ± the standard error of difference. For each time point, asterisks indicated significant differences as determined by a Tukey–Kramer test: *(0.01 < p < 0.05), **(0.001 < p < 0.01) and ***(p < 0.001)
