|---|---|---|---|
| Pretreatment | Transport | pmola | P valueb |
| 25 | 25 | 26.03 + 3.13 | – |

a
The values of IAA transported are the average and se from 13 to 15 plants. The radioactivity transported into the basal 5 mm was determined after 5 h.
b
The P values were obtained by a one-tailed Student's t test for unequal variance with samples compared to the samples with 25°C pretreatment and transport.
