Temporal variations of shoot NO3 −-N (a), soluble sugar (b), free amino acid (c) and soluble protein (d) and root activity (e) of the Pakchoi. Error bars represent standard error (n = 3). CK: Normal fertilization with no γ-PGA application, γ-PGA: Normal fertilization with application of 350.44 mg γ-PGA kg−1 soil. **p < 0.01, *p < 0.05.
