yes, when in bloom from March-June, depending on climate, elevation. It is considered a mild allergen, but for those who suffer from it, it can be quite irritating.
No, they are male trees and only produce pollen
Dates are produced on Date Palm Trees. They have Male and Female forms. The Male trees produce Pollen. They pollen fertilizes the female trees which produce the dates. Commercial groves grow only a few male trees. They take the pollen from them and fertilize the female flowers by hand. Most palms use the wind to spread their pollen but spreading pollen by hand makes fewer male trees necessary. That way more female trees can be grown and more dates produced.
Flowers, trees and shrubs that produce pollen and/or nectar.
Some plants, like grasses and certain trees, do not use insects to carry pollen. Instead they produce large amounts of very small pollen grains which are released into the wind for them to be carried to other plants. Very often, it is this pollen which causes hay fever.
The pollen is to produce acorns, which produce more oak trees.
Probably tree pollen. Many species of trees produce copious quantities of airborne pollen.
The same way as all other plants - pollen. Some species release their pollen into the wind, some need insects to spread it from tree to tree. Some trees produce nuts, some produce seeds. All use pollen.
Trees emit pollen as a means to procreate.
Not all plants need to make seeds. Ferns and mosses for example do not have to produce seeds to spread.
Bees are used to pollinate the trees. As they fly from flower to flower, from tree to tree, pollen attached to the bees is transferred between trees which pollinates them, allowing them to produce fruit.
Do Pine trees help with histamine allergies
flowers produce more pollen grains because the anther makes the pollen it then the stigma collects pollen and the petals of flowers atract insects or birds.
