Warp :: Warp (v. t.) To let the tide or other water in upon (lowlying land), for the purpose of fertilization, by a deposit of warp, or slimy substance..

Parthenogenesis :: Parthenogenesis (n.) The production of new individuals from virgin females by means of ova which have the power of developing without the intervention of the male element; the production, without fertilization, of cells capable of germination. It is one of the phenomena of alternate generation. Cf. Heterogamy, and Metagenesis..

Parthenogenesis :: Parthenogenesis (n.) The production of seed without fertilization, believed to occur through the nonsexual formation of an embryo extraneous to the embrionic vesicle..

Heterogamy :: Heterogamy (n.) The process of fertilization in plants by an indirect or circuitous method; -- opposed to orthogamy.

Intercross :: Intercross (n.) The process or result of cross fertilization between different kinds of animals, or different varieties of plants..

Female :: Female (a.) Having pistils and no stamens; pistillate; or, in cryptogamous plants, capable of receiving fertilization..

Male :: Male (v. t.) Capable of producing fertilization, but not of bearing fruit; -- said of stamens and antheridia, and of the plants, or parts of plants, which bear them..

Grossification :: Grossification (n.) The swelling of the ovary of plants after fertilization. Henslow.

Allogamy :: Allogamy (n.) Fertilization of the pistil of a plant by pollen from another of the same species; cross-fertilization.

Hercogamous :: Hercogamous (a.) Not capable of self-fertilization; -- said of hermaphrodite flowers in which some structural obstacle forbids autogamy.

Orthogamy :: Orthogamy (n.) Direct fertilization in plants, as when the pollen fertilizing the ovules comes from the stamens of the same blossom; -- opposed to heterogamy..

Fecundation :: Fecundation (n.) The act by which, either in animals or plants, material prepared by the generative organs the female organism is brought in contact with matter from the organs of the male, so that a new organism results; impregnation; fertilization..

Polyembryony :: Polyembryony (n.) The production of two or more embryos in one seed, due either to the existence and fertilization of more than one embryonic sac or to the origination of embryos outside of the embryonic sac..

Impregnation :: Impregnation (n.) The fusion of a female germ cell (ovum) with a male germ cell (in animals, a spermatozoon) to form a single new cell endowed with the power of developing into a new individual; fertilization; fecundation..

Carpophyte :: Carpophyte (n.) A flowerless plant which forms a true fruit as the result of fertilization, as the red seaweeds, the Ascomycetes, etc..

Self-fertilization :: Self-fertilization (n.) The fertilization of a flower by pollen from the same flower and without outer aid; autogamy.

Spermatozoid :: Spermatozoid (n.) The male germ cell in animals and plants, the essential element in fertilization; a microscopic animalcule-like particle, usually provided with one or more cilia by which it is capable of active motion. In animals, the familiar type is that of a small, more or less ovoid head, with a delicate threadlike cilium, or tail. Called also spermatozoon. In plants the more usual term is antherozoid..
