The breeding system of Hyacinthoides non-scripta (Asparagaceae): assessing the role of geitonogamy with captive pollinators [PDF]
Plant Ecology and Evolution, 2022 Background and aims – In self-incompatible species, geitonogamous pollen deposition can result in stigma clogging, with negative effects on cross-fertilisation and subsequently reduced fruit and seed set.

Broccoli various genotypes regenerated plants (R0) seed set after geitonogamy
Овощи России, 2020 Relevance. Broccoli cabbage (Brassica oleracea L. convar. botrytis (L.) Alef. var. cymosa Duch.) is widely spread around the world due to its dietetic attribute, preventive and healing effect, cooking simplicity.

Ecology and EvolutionOrchids have evolved diverse reproductive strategies to overcome pollinator limitation and pollen discounting from geitonogamy, particularly in self‐incompatible species. This study compares two coexisting, self‐incompatible orchids (Pholidota articulata

Annals of Botany, 2022 AbstractBackground and AimsEriocaulaceae exhibit a great variety of floral traits associated with insect (e.g. nectariferous structures) and wind pollination (unisexual flowers, exposed sexual organs and small pollen grains), as well as the ‘selfing syndrome’ (small flowers, short distance between stigma and anthers, and temporal overlap of male and ...

Preventing self-fertilization: Insights from Ziziphus species [PDF]
Frontiers in Plant Science, 2023 The fitness of self-progeny individuals is inferior to that of their outcrossed counterparts, resulting in a reduction in a plant population’s ability to survive and reproduce.

Pistillate flowers experience more pollen limitation and less geitonogamy than perfect flowers in a gynomonoecious herb [PDF]
New Phytologist, 2013 Summary Gynomonoecy, a sexual system in which plants have both pistillate (female) flowers and perfect (hermaphroditic) flowers, occurs in at least 15 families, but the differential reproductive strategies of the two flower morphs within one individual remain unclear.

Proceedings of the Royal Society of London. Series B: Biological Sciences, 2004 It has been suggested that the absence of floral rewards in many orchid species causes pollinators to probe fewer flowers on a plant, and thus reduces geitonogamy, i.e. self-pollination between flowers, which may result in inbreeding depression and reduced pollen export.

Journal of Threatened Taxa, 2016 Pavetta indica is a massive bloomer for a brief period in May. The flowers are hermaphroditic, strikingly protandrous, self and cross-compatible, nectariferous and psychophilous. They possess secondary pollen presentation mechanism as a device to avoid
