Hypocotyl lengths of 7-day-old seedlings grown under continuous red (1 μmol m-2·s-1), far red (1 μmol m-2·s-1), or blue (1 μmol m-2·s-1) light. Data comprise 2 biological replicates. Boxplots indicate minimum to maximum values, the 25thto 75thpercentile with lines indicating the median of the data. Statistically significant differences in (D) and (E) were calculated by one-way ANOVA followed by Tukey’s test (p< 0.05), presented in CLD format.
