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 ...

Chemical analysis of peach extrafloral nectary exudate
Phytochemistry, 1986Abstract Analyses of peach leaf nectary exudate confirmed the presence of seven carbohydrates. These included two amino sugars and inositol which have not been previously reported in nectary exudate of plants. Seventeen amino acids, and seven fatty acids were also detected.

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.

Ants and extrafloral nectary‐bearing plants: A dataset of interactions and outcomes
EcologyAbstractExtrafloral nectaries (EFNs) are specialized plant glands that secrete nectar but are not related to pollination. Several ants feed on EFNs and, in exchange, they often attack herbivores, reducing the consumption of leaf tissue and floral parts, and enhancing plant performance.
