Proteomic insights into floral biology
Biochimica et Biophysica Acta (BBA) - Proteins and Proteomics, 2016The flower is the most important biological structure for ensuring angiosperms reproductive success. Not only does the flower contain critical reproductive organs, but the wide variation in morphology, color, and scent has evolved to entice specialized pollinators, and arguably mankind in many cases, to ensure the successful propagation of its species.

Floral Biology and Floral Rewards of Lysimachia (Primulaceae)
American Midland Naturalist, 1983Field and chemical studies have shown that female bees of the genus Macropis (Melittidae) visit flowers of Lysimachia (Primulaceae) in the New World in order to collect liquids secreted by trichome elaiophores at the bases of the petals and/or anther filaments. The association between the genera is not obligatory on the part of the plants.

Floral biology of Ziziphus mauritiana (Rhamnaceae)
Sexual Plant Reproduction, 2009Floral development of the synchronous dichogamous species Ziziphus mauritiana, as followed by light and scanning electron microscopy (SEM), was divided into 11 stages using a series of landmark events. Main cellular events happen synchronously in the female and the male structures, such as meiosis in micro- and macrosporocyte cells, tetrad microspore ...

Floral biology ofTrapa natans var.japonica
The Botanical Magazine Tokyo, 1986The floral behavior and insect visitors ofTrapa natans L. var.japonica Nakai are described. Individual flowers bloom for one day and are visited primarily by Coleoptera and Hemiptera. Exclusion experiments indicate flowers are self- and cross-compatible as well as apomictic. Insect visitors assist in self-pollination as they more within the flower.

American Journal of Botany, 1974
The floral biology of eight species of Magnolia native to the United States is described. The flowers are protogynous. They are pollinated by several species of beetles that enter buds as well as closed and open flowers to feed on nectar, stigmas, pollen, and secretions of the petals.

Carrot Floral Development and Reproductive Biology
2019The defining characteristic of the botanical family of Apiaceae (former Umbelliferae) is the inflorescence. The flowers aggregate in terminal umbels that may be commonly compound, often umbelliform cymes. Likewise, flowers of the carrot are clustered in flat, dense umbels, partially with zygomorphic petals at the edges.

Floral biology of Aristolochia argentina (Aristolochiaceae)
Flora - Morphology, Distribution, Functional Ecology of Plants, 2006Abstract The floral biology of Aristolochia argentina (Aristolochiaceae) was studied in natural populations in Cordoba, Argentina. This native vine has flowers that attract mainly scuttle fly pollinators of the genus Megaselia (Phoridae). The trap-like perianth is formed by a limb, a tube, and a basal utricle.

Floral biology of hybrid zones
2006Abstract Hybridization between closely related species is relatively common in angiosperms and can create a natural hybrid zone. We review recent experimental studies of floral biology in pairs of hybridizing species, emphasizing comparisons of the floral morphology and nectar rewards of hybrid plants with that of their progenitors, and ...

As with nearly all living creatures, humans have always been attracted and intrigued by floral scents. Yet, while we have been manufacturing perfumes for at least 5000 years to serve a myriad of religious, sexual, and medicinal purposes, until very recently, the limitation of our olfactory faculty has greatly hindered our capacity to clearly and ...
