Morfologia floral e biologia reprodutiva de genótipos de aceroleira
(Universidade de São Paulo (USP), Escola Superior de Agricultura Luiz de Queiroz (ESALQ), 2001-09-01)
Estudos sobre morfologia floral e biologia reprodutiva de uma cultura contribuem para o desenvolvimento de técnicas de castração e polinização. Com este propósito, estudaram-se a estrutura e a biologia floral em cinco ...
Relationship of floral morphology and development with the pattern of bee visitation in a species with pollen-flowers, Chamaecrista desvauxii (Fabaceae)
Chamaecrista exhibits a suite of floral traits associated with buzz pollination, and its morphology and organogenesis play crucial roles in pollination because bees can exploit anthers at distinct developmental stages. ...
Genetic variation in the reduction of attractive floral traits of an annual tarweed in response to drought and apical damage
(Oxford University Press, 2015)
Foliar herbivory and water stress may affect floral traits attractive to pollinators. Plant genotypes may differ in their responses to the interplay between these factors, and evolution of phenotypic plasticity could be ...
The roles of rainfall, soil properties, and species traits in flowering phenology along a savanna-seasonally dry tropical forest gradient
We investigated flowering phenology in a semiarid macroclimate along an environmental gradient encompassing neotropical savanna, transition, and seasonally dry tropical forest (SDTF) areas in the Chapada Diamantina Mountains, ...
Spatial and temporal variation in volatile composition suggests olfactory division of labor within the trap flowers of Aristolochia gigantea
(Elsevier Gmbh, 2017-07)
The olfactory components of floral advertisement can be complex, often showing dynamic patterns of emission and chemical composition that may reflect diverse functions related to pollination. In this study we investigated ...
