“According to Dr. O'Toole, people are most at risk from hay fever when the pollen count is high.”

“However, keeping windows and doors closed on days when the pollen count is very high can often help reduce symptoms.”

“When the stigma lobes spread out, this pollen is then deposited on the inner stigmatic surface.”

“Flowers are visited by a diverse pollinator assemblage comprising Hymenoptera, Lepidoptera and Coleoptera.”

“The plant epidermis is a multifunctional tissue playing important roles in water relations, defence and pollinator attraction.”

“Even so, approximately one-third of orchid species have evolved pollination mechanisms whereby the pollinator receives no reward whatsoever.”

“Insects such as bees facilitate pollination as they buzz from plant to plant while feeding on nectar or collecting pollen.”

“Some authors recognize anemophily as the principal pollination system for this family, while others indicate entomophily.”

“The exact same methods developed by growers of rapeseed can be used to control cross pollination from GM crops.”

“In principal, the length of flower anthesis depends on pollination and removal of the pollinium.”

“The stigmatic flaps were gently splayed apart, and a single pollinium was inserted into the stigmatic chamber using the needle.”

“In this latter case we have a pollinium in its most highly developed and perfect condition.”

“A Also known as allergic rhinitis or pollenosis, hay fever is inflammation of the nose, eyes and sinuses.”

“Vittatina-type pollen grain from the gut of another pollinivore, Sojanidelia floralis Rasn., from the same locality, x1 200.”

“As well as pollinating the orchids, the bees are the chief pollinators of canopy trees.”

“Some, including the honey bee, are important pollinators essential for the propagation of plants.”

“What will happen when genetically heterogeneous plant populations are pollinated by new pollinators?”

“Most of the species studied have a pollinarium composed by four superimposed, obovate to rotund, unequal pollinia.”

“Pollination occurs when insects carrying pollinia visit another flower and deposit pollen on the stigma.”

“Only the cosmopolitan syrphid fly Eristalis tenax was captured on two occasions carrying the four pollinia attached to the mouthparts.”

“Such a mutant megagamete could participate in fertilization with wild type pollens and sometimes set aberrant seeds with twin embryos.”

“If you have seasonal hay fever, you may be allergic to pollens released by trees, grasses or weeds.”

“The most common nose or lung allergies are to pollens, molds, dust mites, and cats.”
