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.

Dimorphic enantiostyly and its function for pollination by carpenter bees in a pollen-rewarding Caribbean bloodwort. [PDF]

open access: yesAm J Bot
Abstract Premise Flowers that present their anthers and stigma in close proximity can achieve precise animal‐mediated pollen transfer, but risk self‐pollination. One evolutionary solution is reciprocal herkogamy. Reciprocity of anther and style positions among different plants (i.e., a genetic dimorphism) is common in distylous plants, but very rare in

Duodichogamy and androdioecy in the Chinese Phyllanthaceae Bridelia tomentosa [PDF]

open access: yes, 2007
Flowering plants commonly separate male and female function in time, but rarely are the two stages synchronized within and among individuals. One such temporal mating system is duodichogamy in which each plant produces two batches of male flowers that ...

Sex‐specific floral attraction traits in a sequentially hermaphroditic species

open access: yesEcology and Evolution, 2020
●Many angiosperms are hermaphroditic and produce bisexual flowers in which male (pollen export) and female (stigma receptivity) functions are separated temporally. This sequential hermaphroditism may be associated with variation in flower size, color, or

NECTAR PRODUCTION IN SEVERAL Campanula SPECIES (CAMPANULACEAE)

open access: yesActa Scientiarum Polonorum: Hortorum Cultus, 2018
The flowering, nectar production and sugar content were examined in 2012–2013 seasons for three Campanula species (C. persicifolia L., C. glomerata L., C. trachelium L.). The flowers of all studied Campanula spp. are distinctly protandrous; most of them

Intraspecific Seasonal Variation of Flowering Synchronization in a Heterodichogamous Tree

open access: yesPlants, 2020
Heterodichogamous reproduction in plants involves two flowering morphs, reciprocal in their timing of male and female sexual functions. The degree of synchrony in floral sex phase, within and between individuals of each morph, determines the flowers ...
