The role of jasmonates in floral nectar secretion. [PDF]
PLoS One, 2010 Plants produce nectar in their flowers as a reward for their pollinators and most of our crops depend on insect pollination, but little is known on the physiological control of nectar secretion. Jasmonates are well-known for their effects on senescence, the development and opening of flowers and on plant defences such as extrafloral nectar.

Climate change reduces nectar secretion in two common Mediterranean plants. [PDF]
AoB Plants, 2015 Global warming can lead to considerable impacts on natural plant communities, potentially inducing changes in plant physiology and the quantity and quality of floral rewards, especially nectar. Changes in nectar production can in turn strongly affect plant-pollinator interaction networks-pollinators may potentially benefit under moderate warming ...

Nature, 1877 ME. FRANCIS DARWIN has made an interesting addition to his important discovery of nectar-bearing glands on the young fronds of Pteris aquilina, supplied from the ever-welcome experience of Mr. Fritz Muller. The latter gentleman finds that in Brazil the Pteris aquilina is protected from the leaf-cutting ants by those attracted to the nectar, and Mr ...

Influence of microclimatic conditions on nectar exudation in Glechoma hirsuta W. K [PDF]
, 2005 The nectar production of Glechoma hirsuta W. K. grown under different microclimatic habitat conditions was evaluated by determining the total daily nectar quantity per flower, diurnal dynamics of nectar secretion, the nectar secretion rate, and sugar ...

Nectar and oleiferous trichomes as floral attractants in Bulbophyllum saltatorium Lindl. (Orchidaceae) [PDF]
, 2017 Although many Orchidaceae have deceit flowers that produce no reward, the most common reward, when present, is nectar. Bulbophyllum, however, is unusual in that the labellar secretions of most species investigated to date lack sugars, and, therefore ...

Differential effects of jasmonic acid treatment of Brassica nigra on the attraction of pollinators, parasitoids, and butterflies [PDF]
, 2008 Herbivore-induced plant defences influence the behaviour of herbivores as well as that of their natural enemies. Jasmonic acid is one of the key hormones involved in both these direct and indirect induced defences.
