An increase in pollinator abundance at coffee flowers increased coffee fruit set in rain-fed agro-forests.
Supplemental hand-pollination of otherwise untreated flowers increased initial and final nut set by 66%and44%4%, respectively, indicating substantial pollination limitation.
For events like Mother's Day and Valentine's Day, demand for flowers increases.
Sure, most of us don't eat flowers, but just like any other seasonal product they often need to be imported For events like Mother's Day and Valentine's Day, demand for flowers increases.

As the distance between flowers increases, the bee has to expend considerably more energy in both reheating itself and fuelling the longer flights.
The third strategy of targeting protein synthesis owes its inspiration to ethylene-insensitive flowers, where complete inhibition of protein synthesis in flowers increases flower longevity.
We recently showed that the pink perianth of Ophrys heldreichii flowers increases detectability by its pollinator, males of the long-horned bee Eucera berlandi.
> At the moderately warm temperatures in the climate chamber (∼26.5 29.5 °C) the plants had no empty flowers (producing no nectar) per plant, while at lower and higher temperatures the proportion of empty flowers increased.
The probability of both LPS and Ringer bees choosing the rewarding flowers increases over subsequent visits, i.e the bees learn (visit: colony 1 z=14.59, n=2520, p<0.0001 and colony 2 z=7.84, n=2690, p<0.0001; figure 1).
These studies show that the main mechanisms by which mycorrhizas affect pollinators increased number of flowers, increased flower size or changing pollen and nectar quantity and quality—vary among plant species (Gange and Smith 2005; Cahill et al. 2008; Varga and Kytöviita 2010; Becklin et al. 2011).
