Fig. 4From: Seed characterization and early nitrogen metabolism performance of seedlings from Altiplano and coastal ecotypes of QuinoaThe effect of N deficiency on root morphology in seedlings of C. quinoa. Images of plants subjected to HN (20 mM NO3−) and LN (0.5 mM of NO3−) supplies for 24 days. (a) Tips root length, (b) Primary root length and (c) number of secondary roots. Values are mean ± SE (n = 7). Different letters show statistical differences using two-way ANOVA considering landraces and nutrition treatment (HN and LN) as factors (Fisher LSD test; P < 0.05)Back to article page
