Nectar-Secreting and Nectarless Epidendrum: Structure of the Inner Floral Spur [PDF]

Frontiers in Plant Science, 2018
Epidendrum, the largest genus of Neotropical orchids, contains both nectar-secreting and nectarless species. Here, we compare the fine structure of the inner floral spur, termed the cuniculus, in nectariferous (E. difforme, E. nocturnum,E. porpax, E. rigidum, E. vesicatum) and seemingly nectarless (E. capricornu, E. ciliare, E.

Pollination ecology of the invasive tree tobacco Nicotiana glauca: comparisons across native and non-native ranges [PDF]

, 2012
Interactions with pollinators are thought to play a significant role in determining whether plant species become invasive, and ecologically generalised species are predicted to be more likely to invade than more specialised species.

From Flower to Honey Bouquet: Possible Markers for the Botanical Origin of Robinia Honey

The Scientific World Journal, 2014
Flowers are complex structures devoted to pollinator attraction, through visual as well as chemical signals. As bees collect nectar on flowers to produce honey, some aspects of floral chemistry are transferred to honey, making chemical markers an ...

Cognition-mediated evolution of low-quality floral nectars

Science, 2017
Sweet, but not too sweet Nectar-feeding pollinators, when given a choice, tend to prefer nectar with high concentrations of sugar. Nectar-producing plants, however, tend to produce more dilute nectar. This mismatch between selective force and trait value has long been seen as an evolutionary paradox. Nachev et al.

nectar

, 2017
To establish if foliar herbivory causes changes in floral rewards that could alter floral visitation, we selected another 30 pairs of plants (15 pin and 15 thrum) of P. angustifolia. On each pair, we selected branches with inflorescences at the bud stage

Mutualism and Antagonism in a Post‐Extinction Hawaiian Bird–Lobelioid Pollination System

Ecology and Evolution
Extinction of specialized pollinators can alter the balance between mutualism and antagonism in plant–animal interactions, yet the mechanistic consequences of partner loss remain poorly resolved. We examined plant–bird interactions among three endangered

Systems analyses of key metabolic modules of floral and extrafloral nectaries of cotton [PDF]

, 2019
Nectar is a primary reward mediating plant-animal mutualisms to improve plant fitness and reproductive success. In Gossypium hirsutum (cotton), four distinct trichomatic nectaries develop, one floral and three extrafloral.
