1 Cut off or away.
[no object]Separate by abscission; fall off.
- ‘As the ovules developed, they eventually abscised and fell out, leaving the cupules empty.’
- ‘In several species the flowers never close, as the petals abscise when the flower is still open.’
- ‘The last bract on the spikelet axis has been removed from around the terminal flower, which has an aborted carpel with a two-branched stigma and the filaments of the two stamens, the anthers having abscised.’
- ‘In the present experiments, flower closure was not observed in any of the families in which petals abscise.’
- ‘For example, petals may wilt and abscise more rapidly after pollen deposition on the stigma or pollen tube growth through the style.’
