Distribution and morphology of extrafloral nectaries in some Cucurbitaceae
Botanical Journal of the Linnean Society, 1984A study of extrafloral nectaries has been made in the Cucurbitaceae to ascertain their structure and assess their taxonomic potential. Nineteen species representing nine Old World genera and one New World genus were examined. These included Telfairia occidentalis, Telfairia pedata, Momordica charantia, Lagenaria siceraria, Citrullus lanatus, Luffa ...

EXTRAFLORAL NECTARIES IN EBENACEAE: ANATOMY, MORPHOLOGY, AND DISTRIBUTION
American Journal of Botany, 1984Previous superficial reports, but only one anatomical study of one species, have supported the view that extrafloral nectaries (EFNs) of the unusual Benincasa type (i.e., with several layers of small nectariferous cells) of “Flachnektarien” (surface nectary) are common in Ebenaceae.

THE FUNCTION OF EXTRAFLORAL NECTARIES IN OPUNTIA ACANTHOCARPA (CACTACEAE)
American Journal of Botany, 1979Opuntia acanthocarpa (Cactaceae) possesses extrafloral nectaries embedded in the areoles of new reproductive and vegetative growth. The nectar secreted by these glands attracts ants and is a nutritional food source. Members of one attracted ant species, Crematogaster opuntiae (Myrmicinae), are aggressive and efficient defenders of the plants against ...

Extrafloral Nectaries and Protection by Pugnacious Bodyguards
Annual Review of Ecology and Systematics, 1977Nectar glands. . . are of indirect use by attracting suitable pollinators to flowers, by luring prey to the digestive apparatus of some carnivorous plants, or by maintaining upon the plant a bodyguard of pugnacious insects which more or less efficiently protect it against certain of its enemies....

The morphology and activity of the extrafloral nectaries in Reynoutria × bohemica (Polygonaceae)
Plant Biology, 2019Abstract Reynoutria × bohemica is an invasive species causing significant damage to native ecosystems in North America and Europe. In this work, we performed an in‐depth micromorphological characterisation of the extrafloral nectaries (EFN), during their secretory and post‐secretory phases, in combination with field monitoring of nectary activity ...

The influence of extrafloral nectaries on parasitism of an insect herbivore
American Journal of Botany, 1996The extrafloral nectaries of many plants promote ant defense against insect herbivores. We examined the influence of extrafloral nectaries on the levels of parasitism of a generalist insect herbivore, the gypsy moth (Lymantria dispar L.). Larvae and pupae of the moth were collected from trees with and without extrafloral nectaries growing in the same ...

Extrafloral nectaries in an Australian rainforest: structure and distribution
Australian Journal of Botany, 2003Extrafloral nectaries (EFNs) are of ecological, evolutionary and taxonomic importance in many plants, but are often overlooked in botanical descriptions and have rarely been studied in humid Australian forests. We examined EFNs in a tropical rainforest in northern Queensland, Australia. A total of 29 plant species was found bearing EFNs within the 1-ha

Extrafloral nectaries: ants, herbivores and fecundity in Cassia fasciculata
Oecologia, 1986Extrafloral nectaries of Cassia fasciculata attract nectar feeding ants which protect the plant against leaf herbivores. High ant visitation in late July coincided with high herbivore densities at two sites in east central Iowa. The highest level of leaf herbivory occurred during the time of flowering and early fruit filling, just after the peak of ...

Interaction of Capnodium alfenasii with extrafloral nectaries of Azadirachta indica
ProtoplasmaSooty moulds are saprophytic epiphytic fungi that grow mostly on insect secretions, but they can also be associated with plant secretions. In this study, we aimed to describe de interaction of Capnodium alfenasii sooty mould with the extrafloral shoot nectaries of Azadirachta indica.
