a Schematic diagram of amino-acid feeding of hydroponically grown tea seedlings. Tea seedlings were first cultured under nitrogen deficiency (0 N) for 2 d, and then fed with 1 mM Glu for 5 d, with seedings kept under 0 N as the control. b Total amino-acid contents in the roots of tea seedlings under 0 N or fed 1 mM Glu. c Levels of various amino acids in the roots of tea seedlings under 0 N or fed 1 mM Glu. The data shown are the means ± SDs (n = 3). The asterisks represent statistical significance determined by Student’s t test (*p < 0.05; **p < 0.01)
