Volatile Organic Compounds (VOCs)
Even though emission of specific VOCs (Supplementary Table S4 ) like 2-carene (Figure 10A; t = 2.43, df =18, P = 0.0258), ⍺-phellandrene (Figure 10B; t = 3.514, df = 18,P = 0.0025), β-phellandrene (Figure 10C; t = 2.571, df = 18, P = 0.0192), ⍺-humulene (Figure 10D; t = 2.504, df = 18, P = 0.0221), and β-caryophyllene (Figure 10E; t = 2.637, df = 18, P = 0.0167) decreased post salt treatment, total volatile emission per biomass (ng/g FW) post salt treatment remained unchanged (Figure 10F; P > 0.05). The overall blend of the plant volatiles was not significantly different between no salt and salt treatments (Figure 10G; PERMANOVA (F(1,9) = 2.122, P = 0.1125).
