abscises
v. C2 Proficiency ab·scis·es
v. to fall off a plant or to cut off a part of a plant. This happens naturally when a leaf or flower drops, or it can be done by a gardener.
v. to fall off a plant, typically as a result of natural processes or environmental conditions; to cut off or remove a part of a plant. Often used in botanical contexts to describe the shedding of leaves or the removal of limbs.
The leaves begin to abscise as the weather gets colder.
Gardeners may abscise dead branches to encourage new growth during the spring season.
In many temperate climates, the abscision of leaves is triggered by the shortening of daylight hours and the onset of frost, allowing the plant to conserve energy during the winter months.
