Fig. 6
Morphometric measurements of leaves of wild type, ljnpf2.9–1 and ljnpf2.9–3 mutants grown in the presence of 1 mM and 10 mM KNO3. a leaf area (n = 60). Correspondent trifolia from 20 plants for each genotype have been analyzed. Bars represent mean and standard errors; b cell size (equivalent diameter) of leaves (n = 18). Correspondent trifolia from 3 plants for each genotype have been detached and analyzed. sl = superior lamina; il = inferior lamina. Bars represent the common standard error from two factors ANOVA. Different plant genotypes are indicated. Asterisks indicate significant differences (*p < 0.001;** p < 0.0001)
