apomixis

apomixis Asexual reproduction in plants without fertilization or meiosis. Agamospermy occurs when a diploid embryo sac (sporophyte) develops by the somatic division of a nucellus or integument cell; no meiosis takes place so that the diploid sporophyte gives rise directly to a diploid gametophyte. Apogamy occurs (in ferns) when the converse occurs, a diploid gametophyte giving rise directly to a diploid sporophyte. Apomixis is also used to denote vegetative reproduction in which part of a plant may become detached and develop into a separate individual without any sexual reproduction.

vegetative reproduction

vegetative reproduction Form of asexual reproduction in higher plants. It involves an offshoot or a piece of the original plant (from leaf, stem or root) separating and giving rise to an entire new plant. It may occur naturally, as in strawberries reproducing by runners, or artificially, as in a houseplant-cutting yielding a new plant.

apomixis

apomixis (agamospermy) A reproductive process in plants that superficially resembles normal sexual reproduction but in which there is no fusion of gametes. In apomictic flowering plants there is no fertilization by pollen, and the embryos develop simply by division of a diploid cell of the ovule. See also parthenocarpy; parthenogenesis.
