Table 1.
Control | Treatments Removing apex | NPA | |
IAA concentration (ng g−1 FW) | 82 ± 19 | 59 ± 13 | 37 ± 12 |
JA concentration (ng g−1 FW) | 5.6 ± 0.5 | 133.2 ± 25.2 | 3.7 ± 0.4 |
Samples of different treatments were taken at the same position, either below the cut-surface after excision of the shoot apex, or below the position of NPA application. GC-MS (Trace 2000-Voyager, Finnigan, Thermo-Quest, USA) was employed to analyze IAA and JA concentration. Means ± SE, n = 3.
