Definition of xenogamy in English: xenogamynounzɛˈnɒɡəmizəˈnɑɡəmi mass nounBotany Fertilization of a flower by pollen from a flower on a genetically different plant. Compare with geitonogamy Example sentencesExamples - There are no available data on the breeding system of C. longii to gauge the predominance of autogamy or xenogamy, or seed production due to apomixis.
- Treatment O was conducted to examine xenogamy through artificial pollination using pollen from flowers 5 m away, but within the same population.
- Both species use a mixed breeding system, consisting of xenogamy, geitonogamy, and autogamy; agamospermy is unimportant.
- Likewise, there was no difference between the xenogamy treatment and corresponding controls.
- No differences were noted in pollen germination, pollen tube growth or fertilization between experimental tests of xenogamy and geitonogamy in S. mucugensis.
Derivatives adjective Botany This species is xenogamous and self-compatible. Example sentencesExamples - The pollination biology and flower visitors of Lobelia spicata, an herbaceous prairie perennial, were examined, and this species was found to be xenogamous, self-compatible, and gynodioecious.
- The value of inbreeding depression, measured at the level of seed set as a result of autogamous crosses with respect to xenogamous crosses, was 0 • 019.
- Based upon similarities with other Lobelia species such as L. cardinalis and L. siphilitica it can be predicted that L. spicata is a xenogamous species.
- Tetratheca juncea's predominate breeding system in both populations is a xenogamous one as most fruits were produced when pollen from a different individual was used in the hand-pollination trials.
