List of pollen sources

List of Pollen Sources is a comprehensive catalog of various plants, trees, and flowers that produce pollen, a powdery substance consisting of pollen grains which are male microgametophytes of seed plants. Pollen is a crucial component in the reproduction of plants and is also a significant factor in allergic reactions in humans.

Overview

Pollen is produced by the anther of seed-bearing plants and is disseminated by various means, including wind, water, and animals. The type and quantity of pollen produced by a plant are influenced by its species, environment, and time of year.

Pollen Sources

Trees

Many tree species are significant pollen sources. These include:

• Oak: Oak trees are prolific pollen producers and a major cause of hay fever.
• Pine: Pine trees produce large amounts of pollen, which is often visible as a yellow dust.

Flowers

Flowers are a well-known source of pollen. Some examples include:

• Daisy: Daisies produce pollen that is often collected by bees for honey production.
• Sunflower: Sunflowers are a major pollen source, particularly in agricultural areas.

Grasses

Grasses are another common source of pollen. These include:

• Ryegrass: Ryegrass pollen is a common allergen.
• Bermuda grass: Bermuda grass produces pollen that is a common cause of hay fever.

Pollen and Allergies

Pollen is one of the most common causes of allergies. Many people have an adverse immune response when they inhale pollen, leading to allergic rhinitis, also known as hay fever. Symptoms can include sneezing, itchy or watery eyes, and a runny or stuffy nose.
