Disentangling the role of herkogamy, dichogamy and pollinators in plant reproductive assurance
(Taylor & Francis Ltd, 2018-05)
Autonomous selfing can be favoured by reduced floral herkogamy, dichogamy and pollinator visitation. Autonomous selfing diminishes as pollinator abundance increases; however, the ways pollinators contribute to such result ...
Effects of herkogamy and inbreeding on the mating system of Mimulus luteus in the absence of pollinators
(SPRINGER, 2009-08-23)
Self-pollination mechanisms are often invoked to explain plant reproduction in
environments devoid of pollinators. However, populations may evolve a diverse variety of
strategies depending on the ecological context of ...
Variation in reproductive systems facilitates species boundaries of sympatric Vriesea (Bromeliaceae)
(2017-06-01)
Divergence in reproductive systems among plant species often involves changes in floral traits. The distance separating stigmas and anthers (herkogamy) directly affects the relative importance of reproduction by outcrossing ...
Reproductive biology of Abolboda pulchella and A. poarchon (Xyridaceae: Poales)
(Oxford University Press, 2011-04-01)
Background and Aims Abolboda (Xyridaceae) belongs to the Poales, a predominantly wind-pollinated order whose phylogeny has been widely studied in recent years. The reproductive biology of Abolboda pulchella and A. poarchon ...

Anther-stigma separation in Desmodium species (Papilionoideae-Fabaceae) from northwestern Argentina
(International Society for Horticultural Science, 2011)
The repeated evolutionary transition from outcrossing to self-fertilization in angiosperms has been suggested to occur because selfing provides reproductive assurance. This transition is commonly associated with modifications ...
Reproductive biology of Abolboda pulchella and A. poarchon (Xyridaceae: Poales)
(Oxford University Press, 2013)
Reproductive biology of Habranthus tubispathus
(2013-12)
Habranthus tubispathus is a bulbous species native to the sub humid and semiarid Pampean regions of Argentina, with a high aesthetic ornamental value for sustainable landscaping. In order to initiate breeding programs, the ...
