From: Appropriate NH4 +: NO3 ratio improves low light tolerance of mini Chinese cabbage seedlings

Fig. 1

Effects of NH4 +:NO3 on growth and gas exchange parameters at 9 days after treatment in mini Chinese cabbage leaves under normal (200 μmol m−2 s−1) and low (100 μmol m−2 s−1) light fluences. Mini Chinese cabbage seedlings treated with NH4 +:NO3 ratios for 15 days under normal light fluence (a) and low light fluence (b). The photosynthetic parameters Pn (c), gs (d) and Ci (e) in mini Chinese cabbage seedling leaves were measured at 9 days after NH4 +: NO3 and light fluence treatment. Data represent means of three replicates. Bars indicate the SE. Significant differences (P < 0.05) between treatments are indicated by different letters, for each light condition
