Table 3 Effects of NH4 +:NO3 on levels of glucose, fructose, sucrose and starch at 15 days after NH4 +:NO3 treatment in mini Chinese cabbage under normal (200 μmol m−2 s−1) and low (100 μmol m−2 s−1) light conditions

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