The effect of transferring Arabidopsis at daily intervals (expressed as days from 50% germination) from LD to SD on flowering time. JVP: juvenile phase, AVP: adult vegetative phase, RP: reproductive phase, SD: short day, LD: long day. Vertical error bars denote the standard error of the mean of the number of leaves. Horizontal error bars denote the standard error of the mean of the estimated phase length. Logistic curve (grey curve), maximum slope (black line), lag time (blue lines). The orange dotted lines delimit the three different phases. JVP: tem1 vs. line 75 p = 0.0032; tem1 vs. line 2 p = 0.0043; tem1 vs. line 77 p = 0.0128; line 75 vs. line 2 p = 0.9048; line 75 vs. line 77 p = 0.1574; line 2 vs. line 77 p = 0.298. AVP: tem1 vs. line 75 p = 0.011; tem1 vs. line 2 p = 0.0165; tem1 vs. line 77 p = 0.606; line 75 vs. line 2 p = 0.9048; line 75 vs. line 77 p = 0.025; line 2 vs. line 77 p = 0.0405. Data were analysed by Tukey's multiple comparisons test after two-way ANOVA (p < 0.001).
