| 1. | Ultimately, the abscission layer is responsible for leaf drop.
|
| 2. | The deadwooding process speeds up the tree's natural abscission process.
|
| 3. | Are there two disitinct processes for that and the abscission?
|
| 4. | Might senescence be controlled by temperature and abscission by time?
|
| 5. | The triggering of abscission comes from the end of senescence.
|
| 6. | In peach, PG activity was only detected in fruit abscission zones.
|
| 7. | The abscission layer is a greenish-grayish color.
|
| 8. | Abscission can also occur in premature leaves as a means of plant defense.
|
| 9. | In some situations, abscission may be one means of colonizing exposed sandbars.
|
| 10. | The overexpression of Citron-K and of anillin leads to abscission delay.
