Definition of apomixis in English:
noun[mass noun] Botany
Asexual reproduction in plants, in particular agamospermy. Often contrasted with amphimixis.
- Another example is the major impact that understanding apomixis would have on plant breeding.
- During in vivo development, maternal apomixis refers to the asexual formation of a seed from the maternal tissues of the ovule, avoiding the processes of meiosis and fertilization.
- It is noteworthy that according to the studies of Illg, M. brasiliensis may be apomictic, although pollinator-dependent; i.e. apomixis is triggered by pollen-tube development.
- Example sentences
- Maternal apomictic embryos develop from a somatic cell within the ovule or from an unreduced embryo sac derived from the megaspore mother cell (diplospory).
- The results show that early fertilization leads to the formation of apomictic embryos while fertilization at anthesis favours the formation of sexually derived embryos.
- Furthermore, apomictic reproduction has been found in most polyploid Corollinae species, which, if transferred to cultivated beet, has the potential to improve the fixation of desired genotypes in breeding programmes.
