It too seems to be effectively pollinated by honey bees and native larger-bodied generalist bees that scrabble at the anthers
for pollen, as well as by nectar-foraging hummingbirds (Mitchell, 1989).
Breidy, the seed bank director at the Lebanese Agricultural Research Institute, cuts open the spikelets from one ear of wheat, removes the anthers

Floral biology refers to a comprehensive study of flowers which includes anthesis, dehiscence of anthers
, pollen fertility and stigma receptivity (Kalloo, 1988).
This stamen will be conspicuously smaller than the other stamen primordia for a substantial period of early development and will be the last of the stamens to differentiate into filament and anther
Some authors have suggested that co-occurring plants with poricidal anthers
