Definition of self-incompatible in English: self-incompatibleadjective Botany (of a plant or species) unable to be fertilized by its own pollen. Example sentencesExamples - However, there are a significant number of exceptions to the UI ‘rule’ that pistils of self-incompatible taxa inhibit pollen from self-compatible taxa.
- Many plant species are capable of self-fertilization and even highly self-incompatible species may show varying levels of self-fertility.
- In particular, seed and fruit production of self-incompatible species rely on flowering times of compatible genotypes overlapping, with important economic consequences for agriculture.
- Clusters of genetically identical plants, for example, limit the number of mates available to self-incompatible species with limited pollen dispersal.
- Ideally seed orchards should contain only self-incompatible trees to eliminate production of selfed seed.
Derivatives noun Botany They may also have roles in pollen tube self-incompatibility and in plant defence responses. Example sentencesExamples - On the other hand, recent studies have pointed out the existence of late-acting self-incompatibility, in which self-pollen rejection occurs after the pollen tubes enter the ovary.
- Gametophytic self-incompatibility is a widespread mechanism in flowering plants that prevents self-fertilization and promotes out-crossing.
- This cryptic self-incompatibility may effectively reduce geitonogamous self-fertilization, because stigmas probably receive outcross and geitonogamous pollen simultaneously.
- It is reasonable to conclude that there are at least three separate origins of gametophytic self-incompatibility in angiosperms.
