From: Differential contributions of NO3/NH4+ to nitrogen use in response to a variable inorganic nitrogen supply in plantlets of two Brassicaceae species in vitro

Fig. 4

The contribution of the nitrate (a) and ammonium utilization (b) to total inorganic nitrogen assimilation for the Ov and Bn plantlets cultured under different inorganic nitrogen concentrations. Ov Orychophragmus violaceus, Bn Brassica napus. The ratio of nitrate to ammonium within each inorganic nitrogen concentration was 2:1. The error bars was the result which was calculated by the error propagation formula
