| Wild type (WS) | cin5-1 | eto2-1 | |
| Seedlings | |||
| Etiolated | 1.8 ± 3.5 | 1.2 ± 2.0 | 33.2 ± 3.2 |
| Light-grown | 11.6 ± 0.7 | 11.2 ± 1.2 | 15.7 ± 0.4 |
| Adult tissues | |||
| Flowers | 39.0 ± 5.8 | 44.0 ± 4.3 | 47.5 ± 8.0 |
| Siliques | 19.7 ± 2.4 | 19.8 ± 5.0 | 13.4 ± 3.0 |
| Leaves | 1.6 ± 0.4 | 1.4 ± 0.2 | 2.0 ± 0.2 |
The mean of at least three independent replicates ± SD. Seedlings were grown or excised tissue placed in vials containing 3 ml of MS agar. The vials were flushed with hydrocarbon-free air, sealed, and incubated at 23°C (3 days for seedlings, 7 h for tissue), and the accumulated ethylene was measured.
