Table 2 Contents of free amino acids (mg/g fresh weight) in the leaves of tea plant treated with methionine sulfoximine (MSX). The value shown is mean ± standard deviation (SD). CK indicates plants grown with nutrient solution without MSX treated, while MSX indicate plants treated with MSX. The asterisk indicates significant difference between MSX and CK group (*P < 0.05, **P < 0.01 in student’s t-test). For each treatment 3 biological replicates were used
