Disentangling the role of herkogamy, dichogamy and pollinators in plant reproductive assurance [PDF]

Plant Ecology and Diversity, 2018
Background: Autonomous selfing can be favoured by reduced floral herkogamy, dichogamy and pollinator visitation.

Linking self-incompatibility, dichogamy, and flowering synchrony in two Euphorbia species: alternative mechanisms for avoiding self-fertilization? [PDF]

PLoS ONE, 2011
Plant species have several mechanisms to avoid selfing such as dichogamy or a self-incompatibility response. Dichogamy in a single flower may reduce autogamy but, to avoid geitonogamy, plants must show flowering synchronization among all their flowers (i.

Protandrous-protogynous dimorphism in indigenous selections from North Western India and some exotic cultivars of Persian walnut (Juglans regia L.) [PDF]

Advances in Horticultural Science, 2013
Walnut (Juglans regia L.) is one of the most important temperate nuts grown worldwide. In India, however, most of the produce comes from age-old trees of unknown origin.

THE EFFECT OF SEASON ON DICHOGAMY PATTERNS IN PECAN. [PDF]

HortScience, 1993
Thirteen cultivars of pecan [Carya illinoinensis (Wangenh.) K. Koch] were monitored for bud break, pollen shed and stigma receptivity for 4 years at LSU Pecan Station, Robson, LA. Cultivars were generally consistent in displaying clear patterns of protogyny or protandry, although patterns ...

Timing is everything: Dichogamy and pollen germinability underlie variation in autonomous selfing among populations [PDF]

American Journal of Botany, 2018
Premise of the StudyThe evolution of multiple floral traits often underlies the transition from outcrossing to selfing. Such traits can influence the ability to self, and the timing at which selfing occurs, which in turn affects the costs of selfing. Species that display variation in autonomous selfing provide an opportunity to dissect the phenotypic ...

Does size matter? Pollination biology of Aristolochia sessilifolia (Aristolochiaceae) [PDF]

Plant Ecology and Evolution
Background and aims – The morphology of flowers with specialized pollination acts as a pollinator filter, resulting in compatibility between the flower and its visitors. These characteristics can influence plant diversity, and studying these interactions
