Definition of autogamy in English:

autogamy

noun ɔːˈtɒɡəmi

Biology

Self-fertilization, especially the self pollination of a flower.
〔生〕自体受精（尤指自花受精）。比较ALLOGAMY
Compare with allogamy
Example sentencesExamples
- Recently several populations and species of Antirrhinum were characterized for their percentage of autogamy and self-fertility, and large variation was observed.
- Together, the three modes of geitonogamy make a much larger contribution to self-fertilization than autogamy.
- Recipients were cells from young clones only four to six fissions after the last autogamy.
- Both species use a mixed breeding system, consisting of xenogamy, geitonogamy, and autogamy.
- In both years seed set was significantly lower in the autonomous autogamy treatment than in the corresponding controls.
- In this study, I use floral manipulations in conjunction with marker gene analysis to estimate the relative contributions of autogamy and geitonogamy to self fertilization.
- Changes in floral morphology are normally required to promote either autogamy or allogamy.

Derivatives

autogamous

adjective

Biology

Like tomato and pepper, eggplant is an autogamous diploid with 12 chromosomes.
Example sentencesExamples
- I estimated the amount of autogamous pollination by comparing the stigmatic pollen loads of intact and emasculated flowers.
- The success of hybrid maize has produced interest in developing hybrids in autogamous crops.
- Wild barley is a predominantly autogamous annual grass.
- Unlike maize, rice is predominantly autogamous and, hence, gene flow is restricted.
- Consequently, an increase in autogamous self-pollination may be achieved with little reduction of outcrossed male fitness.

Origin

Late 19th century: from auto-¹ 'self' + Greek -gamia (from gamos 'marriage').
