Control (C) | Mycorrhizal (M) | Ratio M/C | |
---|---|---|---|
Free ABA | 99 ± 2.8a | 137 ± 19.2b | 1.38 |
ABA-GE | 1598 ± 284.7a | 311 ± 27.7b | 0.19 |
DPA | 276 ± 41a | 228 ± 80a | 0.82 |
PA | 59 ± 2.13a | 9 ± 0.3b | 0.15 |
7′OH-ABA | ND | 8 ± 3.3a | ≥8 |
neo-PA | 13 ± 3.1a | 5 ± 0.9b | 0.38 |
Levels of ABA, ABA-GE, DPA, PA, 7′ OH-ABA and neo-PA were measured by UPLC-ESI(+)-MS/MS from roots of non-mycorrhizal (control) and mycorrhizal plants 50 days after inoculation with Rhizophagus irregularis. Values correspond to mean ± SE (n = 5). For each compound values with same letters do not significantly differ (P = 0.05) according to Duncan’s multiple range test.
