Table 1.

IAA and JA concentration in stem tissue 90 min after removing the shoot apex or 210 min after application of NPA

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.
