From: MeJA-mediated enhancement of salt-tolerance of Populus wutunensis by 5-aminolevulinic acid
The MDA content, the REC and antioxidant enzyme activities of P. wutunensis seedlings under different treatments. (A) MDA content; (B) REC; (C) SOD activity; (D) POD activity; (E) CAT activity. CK: normal growth; S: salt stress; SA: salt stress + ALA; SMJ100: salt stress + 100 µM MeJA; (5) SMJ200: salt stress + 200 µM MeJA; (6) SMJ400: salt stress + 400 µM MeJA; (7) SS: salt stress + 200 µM SHAM; (8) SSA: salt stress + 200 µM SHAM + ALA. Data were expressed as the mean ± standard error of three independent biological replicates. Different letters indicated significant differences of P < 0.05 according to Duncan test
