Effects of MeJA on nitrogen metabolism of L. longituba seedlings. (A) The nitrate reductase (NR) activities in MJ-0 and MJ-75 treatments. (B) The glutamine synthetase (GS) activities in MJ-0 and MJ-75 treatments. (C) The glutamate synthase (GOGAT) activities in MJ-0 and MJ-75 treatments. Error values indicate the standard deviation (SD). Least-significant difference test (LSD, p < 0.05) was used to compare the means. Different letters represent significant differences between groups (N = 3, p < 0.05).
