|---|---|---|---|---|---|---|---|
| No ACC | 10.6 ± 0.6 | 9.7 ± 0.2 | 6.9 ± 0.1 | NDf | ND | 5.0 ± 0.2 | 2.1 ± 0.1 |

a
The unit of measure for hypocotyl length is mm.
b
Seedlings were grown for 4 d in the dark in either the presence or absence of ACC.
c
Mean ± se values were determined from 15 individuals.
d
Mean ± se values were determined from 102 individuals.
e
Mean ± se values were determined from 37 individuals.
f
ND, Not determined in this experiment.
