Sequential decline in allocation among flowers within inflorescences: Proximate mechanisms and adaptive significance

Article Topic(s): Seed increase,Seed collecting
Research Setting(s): Greenhouse
Species Referenced: Aquilegia canadensis (Eastern red columbine),
AbstractExamines the mechanisms and effects of declining resource allocation in Aquilegia canadensis flowers over a period of time. Architectural effects resulted in a small decline in ovule and pollen production with flower sequence. Competition for resources among flowers resulted in a stronger decline in fruit set and numbers of seeds per fruit. Defoliating plants greatly reduced fruit set and seeds per fruit, while experimentally adding resources to during early flowering resulted in increased seed production of later flowers. Higher allocation to early flowers may be a response to herbivory, which affects later flowers more than early flowers.
