Figure 7.

A and B, Effects of 120 h of treatment with 10 μm ACC and 10 μm AVG on mean LR length (A) and LR number (B) under homogeneous feeding of N (1 mm) in oilseed rape seedlings. C, Changes induced by 10 μm ACC and 10 μm AVG root treatments on the correlation established between primary root length and LR number. Vertical bars indicate ± se for n = 3 repeats of the sum of four seedlings each when larger than the symbol. Data were analyzed by the nonparametric test of Kruskall Wallis. Then, Mood median tests were to compare means or medians; bars sharing different letters are significantly different at P = 0.05 (Sokal and Rohlf, 2003).
