Temporal variations of fresh weight (FW, a,b), total carbon (TC, c,d), total nitrogen (TN, e,f), total phosphorus (TP, g,h) and total potassium (TK, i,j) in the shoot and root tissues, respectively, 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.
