High floral bud abscission and lack of open flower abscission in Dendrobium cv. Miss Teen: rapid reduction of ethylene sensitivity in the abscission zone

, 2006
We studied the abscission of floral buds and open flowers in cut Dendrobium inflorescences. Abscission of floral buds was high and sensitive to ethylene in all cultivars studied. Many open flowers abscised in most cultivars, but cv. Willie exhibited only

Two abscission zones proximal to Lansium domesticum fruit: one more sensitive to exogenous ethylene than the other

Frontiers in Plant Science, 2015
Longkong (Lansium domesticum) fruit grows in bunches and is also sold as bunches. Individual fruit can separate from the bunch both before and after commercial harvest. The fruit has two separation sites.

Early evolutionary history of the seed

Biological Reviews, Volume 101, Issue 3, Page 1511-1553, June 2026.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Climate Warming Will Reduce Boreal Forest Litterfall, but the Response Differs Among Plant Functional Types

Ecology and Evolution, Volume 16, Issue 6, June 2026.
We synthesized boreal litterfall data from published studies and applied generalized additive models to examine how stand age‐ and temperature‐related litterfall dynamics varies across plant functional types, and to project future trends under climate change.

Auxin transport inhibition triggers pedicel expansion and alters abscission zone dynamics in tomato fruit. [PDF]

Auxin transport plays a key role in plant growth and organ abscission by regulating cell division and tissue diferentiation. In this study, we investigated the efects of 2,3,5-triiodobenzoic acid (TIBA), an auxin transport inhibitor, on tomato pedicel ...

Immediate response of soil nitrogen cycling‐related enzyme activities to typhoon disturbance along a gap size gradient

Ecosphere, Volume 17, Issue 6, June 2026.
Abstract Although heavy rainfall and the input of unsenescent litter produced by tropical cyclones can profoundly affect the activities of soil nitrogen (N) cycling‐related enzymes in coastal mountain forest ecosystems in the short term, the immediate responses of these enzymes to typhoon disturbances and the underlying mechanism remain unknown.

Early gene expression events in the laminar abscission zone of abscission-promoted citrus leaves after a cycle of water stress/rehydration: involvement of CitbHLH1. [PDF]

, 2012
Leaf abscission is a common response of plants to drought stress. Some species, such as citrus, have evolved a specific behaviour in this respect, keeping their leaves attached to the plant body during water stress until this is released by irrigation or
