A and B, Twenty-four-hour elongation responses of primary roots of oilseed rape seedlings treated with different doses of AIBA or AVG (n = 12–16 seedlings; A) or cotreated with different doses of AVG or AVG + 1 mm Glu under homogeneous feeding of 1 mm N (n = 1–4 experiments of n = 12–16 seedlings; B). C, Restoration effects of 72-h cotreatments with 3 μm AVG + 1 mm Glu or 10 μm AVG + 1 mm Glu on root hair lengths in 24-h neo-elongated primary root between 48 and 72 h of treatment (n = 72; see experimental procedure in Fig. 1A). Each bar indicates ± se when larger than the symbol. Mood median tests were used to compare means or medians; bars sharing different letters are significantly different at P = 0.05 (Sokal and Rohlf, 2003).
