Definition of autogamy in English: autogamynoun ɔːˈtɒɡəmi Biology Self-fertilization, especially the self pollination of a flower. 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 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').
