Flower trade-offs derived from nectar investment in female reproduction of two Nicotiana species (Solanaceae) Acta Botanica
Galetto,Leonardo; Araujo,Francielle Paulina; Grilli,Gabriel; Amarilla,Leonardo D.; Torres,Carolina; Sazima,Marlies.
ABSTRACT Animal-pollinated flowers may orient resources for competing activities, such as nectar production for attracting flower visitors but then saving nectar (through inhibiting nectar production or by final resorption) for the subsequent maturation of fruits and seeds. Nectar production is continuous in Nicotiana longiflora and N. alata after flower opening, but early nectar removal reduces total secreted nectar. Resource trade-off between nectar investment and seed production were experimentally assessed in manually pollinated flowers experiencing different numbers of repeated nectar removals, while controlling for maternal effects. We expected that flowers with less nectar secretion produce larger seed sets. The results showed that for both species...
