Pollen in a sentence

Ms Dowling said that tree pollen, grass pollen, weed pollen – which all emerge at different points in the year – could trigger a bout of hay fever.

Pollen main Bees collect pollen in their pollen baskets and carry it back to the hive.

Secondary pollen presentation (also known as stylar pollen presentation or ixoroid pollen mechanism) is especially known from the Gardenieae and related tribes.

The pollen is transferred on appendages on the adults, which fly to the next flower to feed and unwittingly deposit the pollen on the stigma of the next flower, where the pollen germinates and fertilizes the seeds.

Cronin, who also suffers from pollen allergies, said another factor is that in recent decades many non-native plants have been introduced to the Lehigh Valley and many long-time residents may not have strong immunity to their pollen.

Forecasters have said to expect UV and pollen counts to be high all weekend, so it is still advisable to slap on the suncream and hay fever sufferers should take heed as it is peak season for grass pollen now.

They’re the pollen producers, releasing clouds of pollen into the air that sometimes trigger hayfever.

This means you'll be given small amounts of pollen as an injection or tablet to slowly build up your immunity to pollen.

This pollen is a major trigger for asthma and allergic rhinitis (hay fever) and high levels of pollen contributed to the state’s Thunderstorm Asthma (TSA) Epidemic in 2016.

When honey bees visit plants to collect nectar and pollen, static electricity from hairs all over their bodies attracts pollen.

Allergy expert Max Wiseberg warned: “When the tree pollen season is delayed, more trees are likely to release their pollen at the same time, creating a time bomb waiting to explode.

Since they keep the pollen dry, it falls off easily when the bee flies from flower to flower, making them a much more efficient pollinator than a honeybee, who tucks pollen in ‘baskets’ in its hind legs.

The mystery in the first story of this issue surrounds who has stolen the pollen from the mutant flowers; the pollen is now a global street drug.

The Twin Cities is a pollen hot spot, according to the Weather Channel, with “very high” levels of tree pollen.

They use fuzzy hairs on their bodies and pollen baskets on their legs to carry the protein-rich resource, but some pollen drops off at each flower.

This year saw some of the highest recorded pollen counts in history, which had cities from Europe to the US covered in clouds of pollen as a result of global warming.

Around 95 per cent of hay fever sufferers are triggered by grass pollen, but most grasses will not start releasing significant quantities of pollen into the air until towards the end of May.

During pollen season every cubic metre of air contains somewhere between 10 and 1,000 grains of pollen.

Pollen from trees, grasses and weeds are the offenders listed in the pollen count on The Columbian’s weather page.

After pollination, a tube grows from the pollen through the stigma into the ovary to the ovule and two sperm are transferred from the pollen to the megagametophyte.
