Andromonoecy and buzz pollination in Solanum species (Solanaceae) endemic to the Canary Islands

open access: yesAnales del Jardín Botánico de Madrid, 2006
We investigated the pollination and reproductive biology of two Canary Island endemics, Solanum vespertilio and S. lidii (Solanaceae). We measured male function (pollen development), female function (fruit initiation) and spatial arrangement of ...

Functional Dioecy and Andromonoecy in Solanum [PDF]

open access: yesEvolution; International Journal of Organic Evolution, 1989
Field and laboratory studies of 19 diclinous species endemic to Australia help to clarify the nature and evolution of andromonoecy, androdioecy, and dioecy in the genus Solanum. Ten species are andromonoecious; typically these species bear inflorescences with a single, large basal hermaphroditic flower and 12-60 distal, smaller staminate flowers.

Andromonoecy and developmental plasticity in Chaerophyllum bulbosum (Apiaceae-Apioideae). [PDF]

open access: yesAnn Bot, 2013
Andromonoecy, the presence of hermaphrodite and male flowers in the same individual, is genetically fixed or induced, e.g. by fruit set. Little is known about the forces triggering andromonoecy in the Apiaceae. In the present study, a natural population of the protandrous Chaerophyllum bulbosum was investigated to elucidate architectural constraints ...

Functional Andromonoecy in Euphorbia (Euphorbiaceae) [PDF]

open access: yesAnnals of Botany, 2002
The occurrence of cyathia containing staminate flowers but lacking a pistillate flower was studied in 17 species of Euphorbia. Male cyathia were found in the majority of species studied (88.2%) giving functional andromonoecy. In the male cyathia, the pistillate flower is generally totally absent, but sometimes a vestigial pistillate flower with a non ...

Andromonoecy of Aegopodium podagraria (Apiaceae) in Moscow region [PDF]

open access: yesVestnik Tomskogo gosudarstvennogo universiteta. Biologiya, 2019
Рассмотрены особенности проявления андромоноэции у длиннокорневищного травянистого поликарпического растения Aegopodium podagraria. Выявлено, что у A. podagraria в пределах одной особи образуются два типа цветков – обоеполые и тычиночные, которые имеют ...

Is increased male flower production a strategy for avoidance of predispersal seed predation in andromonoecious plants?

open access: yesEcology and Evolution, 2021
Floral gender in angiosperms often varies within and among populations. We conducted a field survey to test how predispersal seed predation affects sex allocation in an andromonoecious alpine herb Peucedanum multivittatum.

Andromonoecy in Solanum lycocarpum A. St . ‐ Hil . ( Solanaceae ): Floral attributes, visitors and variation in sexual expression over time [PDF]

open access: yesPlant Species Biology, 2021
: Sexual expression in andromonoecious species—those in which a single 19 individual can bear both staminate and hermaphroditic flowers—may vary among reproductive 20 events in the same plant, among individuals, and across populations.

Seasonal change of flower sex ratio and pollinator dynamics in three reproductive ecotypes of protandrous plant

open access: yesEcosphere, 2020
Cimicifuga simplex has three genetically and ecologically distinct pollination morphs with different flowering phenology, flower sex expressions, and selfing rates. A previous study showed that strong protandry in hermaphroditic flowers of C.

A Dual-Successive-Screen Model at Pollen/Stigma and Pollen Tube/Ovary Explaining Paradoxical Self-Incompatibility Diagnosis in the Olive Tree—An Interpretative Update of the Literature [PDF]

open access: yesPlants, 2021
The ‘pollen test’ and ‘fruit set test’ following controlled crossing combinations of parents are the most commonly used methods for pollination incompatibility studies in Olea europaea L. Self-incompatibility (SI), with diagnoses based on the pollen test
