The gas chromatography-mass spectrometry (GC-MS) analysis of the SFA and UFA contents of poplar leaves before and after drought or salt stress. (A) The contents of C14-C17 SFAs and UFAs in poplar leaves cultivated under normal conditions and drought or salt stress. (B) The contents of C18-C24 SFAs and UFAs in poplar leaves cultivated under normal conditions and drought or salt stress. Three biological replicates were performed per group. * p < 0.05, ** p < 0.01, *** p < 0.001 compared to control poplar. The kinds of SFAs and UFAs included myristate (C_14:0), cis-9-tetradecenoate (C_14:1), pentadecanoate (C_15:0), cis-10-pentadecenoate (C_15:1), palmitate (C_16:0), palmitoleate (C_16:1), margarate (C_17:0), cis-10-heptadecenoate (C_17:1), octadecanoate (C_18:0), oleate (C_18:1), linoleic acid (C_18:2), linolenic acid (C_18:3), icosanoate (C_20:0), eicosenoate (cis-11) (C_20:1), eicosadienoate (cis-11, 14) (C_20:2), eicosatrienoate (cis-8,11,14) (C_20:3), behenate (C_22:0), erucate (C_22:1), lignocerate (C_24:0), and nervate (C_24:1).
