The functional roles of 3D heterostyly and floral visitors in the reproductive biology of Turnera subulata (Turneroideae: Passifloraceae)
(2020-03-01)
Heterostyly is a floral polymorphism that reduces conflicts between sexual functions (sexual interference), such as self-pollination in self-incompatible flowers and loss of pollen to incompatible stigmas. In many distylous ...
Pollinator response to flower color polymorphism and floral display in a plant with a single-locus floral color polymorphism: consequences for plant reproduction
(Springer Tokyo, 2012-03)
Variation in flower color, particularly polymorphism, in which two or more different flower color phenotypes occur in the same population or species, may be affected or maintained by mechanisms that depend on pollinators. ...
Nectary structure and ultrastructure in two floral morphs of koelreuteria elegans subsp. formosana (sapindaceae)
(Elsevier Gmbh, 2017)
The structure and ultrastructure of the floral nectary of staminate and pistillate flowers of Koelreuteria
elegans subsp. formosana (Sapindaceae, Koelreuterieae) were studied. In both floral morphs, the floral
nectary ...
Reproductive biology of Echinodorus longipetalus (Alismataceae): Sexual morphs, breeding system and pollinators
(ELSEVIER SCIENCE BV, 2008)
The floral biology, pollinators and breeding system of Echinodorus longipetalus Micheli were studied in a marshy area of the district of Taquaritinga (State of Sao Paulo), southeastern Brazil. E. longipetalus is gynodioecious ...
Anther structure and pollen development in Melicoccus lepidopetalus (Sapindaceae): an evolutionary approach to dioecy in the family
(Elsevier Gmbh, 2012-10)
Anther and pollen development in staminate and pistillate flowers of dioecious Melicoccus lepidopetalus (Sapindaceae) were examined by light and electron microscopy. Young anthers are similar in both types of flowers; they ...
Phenological match drives pollen-mediated gene flow in a temporally dimorphic tree
(Wiley Blackwell Publishing, Inc, 2018-01)
Variation in flowering phenology is common in natural populations, and is expected to be, together with inter-mate distance, an important driver of effective pollen dispersal. In populations composed of plants with temporally ...
