- Observation Upright decapitated maize coleoptile segments showed strong spontaneous growth after three hours.
- Intervention effect Inversion markedly reduced the latent period of spontaneous growth in decapitated segments.
- Observation Upright segments with intact tips had a weak transient spontaneous growth response.
- Intervention effect Inverted segments with intact tips showed a typical spontaneous growth response.
- Mechanism The data contradicted a time-dependent increase in auxin sensitivity as the cause of spontaneous growth.
