Exogenous glycine inhibits root elongation and reduces nitrate-N uptake in pak choi (<i>Brassica campestris</i> ssp. <i>Chinensis</i> L.) - Fig 5

Effect of the ethylene synthesis inhibitors (A) AVG and (B) AgNO3 on the inhibition of primary root length induced by exogenous Gly. Pak choi seedlings were grown on axenic agar medium containing 10 mM NO3--N with 2.5 mM Gly and various concentrations of AVG (0–10 μM) or AgNO3 (0–50 μM) for 5 d. Data are mean ± SE (n = 5). Different letters indicate significant differences at P LSD test.
