From: Nitrogen physiology of contrasting genotypes of Chenopodium quinoa Willd. (Amaranthaceae)
A/Ci curves [net CO2 assimilation rate (A) versus CO2 concentration (Ci)] of three genotypes of Chenopodium quinoa growing under different N supplies. Fully expanded third leaves (from the top) were used for the photosynthetic measurements two weeks after flowering. A/Ci curves of (a) Faro, (b) UdeC9 and (c) BO78 are shown. Values are mean ± SE (n = 4). Significant differences between N supply within a genotype are indicated by asterisks at a P < 0.05 using one-way ANOVA.
