Abscission
The abscission layer is a greenish-greyish color. Abscission can also occur in premature leaves as a means of plant defense. Situated on both sides of the abscission zone are layers of parenchyma cells, which produce and inject suberin and lignin under the abscission zone into wikipedia.org

Cladoptosis
As in leaf shedding, an abscission layer forms, and the branch is shed cleanly. See also Abscission Marcescence: the opposite phenomenon – withered branches (or leaves) stay on References Further reading External links Cladoptosis wikipedia.org

秋叶
秋叶的变化主要有变色(discoloration)及脱落(abscission): 变色 当秋季来临时,日照减少及气温降低使得叶基慢慢形成一层特殊的木栓细胞,进而使叶脉逐渐闭合,最后便无法供应水分及矿物质,叶绿素也随之降解,叶绿素内的氮元素及其他养分,会被回收而转运至茎与根。 脱落 当光合作用因叶绿素降解而减少,叶柄基部会分化为离区(abscission zone)。 wikipedia.org

Midbody (cell biology)
The midbody is important for completing the final stages of cytokinesis, a process called abscission. During symmetric abscission, the midbody is severed at each end and released into the cellular environment. wikipedia.org
