ARCHITECTURAL EFFECTS AND THE INTERPRETATION OF PATTERNS OF FRUIT AND SEED DEVELOPMENT
The commonly observed proximal-to-distal decrease within inflorescences of fruit and/or seed maturation per flower has frequently been attributed to competition among developing fruits for resources.Expand

Multiple developmental processes underlie sex differentiation in angiosperms.
The production of unisexual flowers has evolved numerous times in dioecious and monoecious plant taxa. Based on repeated evolutionary origins, a great variety of developmental and genetic mechanismsExpand

  • International Journal of Plant Sciences
  • 1 November 1997
Floral form and function commonly vary quantitatively and qualitatively within inflorescences. Overall floral size, the sizes of individual floral organs, and the frequency of successful fruit and/orExpand

Clonal Diversity in Alpine Populations of Polygonum viviparum (Polygonaceae)
Asexual reproduction is extremely common among arctic and alpine species, and successful sexual reproduction may be rare. In asexual populations, the absence of segregation and recombination predictsExpand

Diversification of andromonoecy in Solanum section Lasiocarpa (Solanaceae): the roles of phenotypic plasticity and architecture.
Quantitative analyses of sexual expression show extensive interspecific variation in the strength of andromonoecy (proportions of hermaphroditic and staminate flowers) among Solanum species in theExpand

Architectural effects mimic floral sexual dimorphism in Solanum (Solanaceae).
Factors underlying apparent floral sexual dimorphism were examined in six species of andromonoecious Solanum section Lasiocarpa (Solanaceae). Both multivariate and univariate analyses show thatExpand

Mechanisms of differential pollen donor performance in wild radish, Raphanus sativus (Brassicaceae).
In order to understand the characters on which sexual selection might operate in plants, it is critical to assess the mechanisms by which pollen competition and mate choice occur. To address thisExpand

DEVELOPMENTAL PLASTICITY, GENETIC VARIATION, AND THE EVOLUTION OF ANDROMONOECY IN SOLANUM HIRTUM (SOLANACEAE)
Studies of andromonoecious species have shown that sex expression (proportions of hermaphrodite and staminate flowers) is quite variable. It is not known, however, whether this variation is due toExpand
