Photosynthetic characteristics of the Bn and Ov seedlings under simulated karst habitats. Pn-Photosynthetic rate, Cond-Stomatal conductivity, Tr-Transpiration, Ci-Intercellular CO2, WUE-water use efficiency, Bn-Brassica napus, and Ov-Orychophragmus violaceus. The bicarbonate was denoted as B0 (HCO3−: 0 mM), and B10 (HCO3−:10 mM). Nitrogen was denoted as N0(no nitrogen), N19 (nitrate:ammonium = 1 mM: 9 mM), N55 (nitrate:ammonium = 5 mM: 5 mM), and N91 (nitrate:ammonium = 9 mM: 1 mM). Each value represents the mean ± SD (n = 3). The mean values marked with different letters (a,b,c,d) significantly differ at P < 0.05
