Comparison of Ambrosia L. Pollen Seasons in Lublin (Poland) and Ivano-Frankivsk (Ukraine) and Presentation of the Morphotypes of Trichomes on A. artemisiifolia L. Shoots in Terms of the Allergenic Properties of the Plant

Ambrosia pollen contains strong allergens. Allergic reactions can also be caused by direct contact with the plant. The investigations of dynamics seasons were conducted in Lublin (Poland) and Ivano-Frankivsk (Ukraine) 2013–2015. onset end seasons, maximum concentrations, annual sums, number days an allergy risk determined. Additionally, types trichomes present on different parts artemisiifolia L. shoots determined using light microscopy. Morphometric studies carried out sampled from staminate inflorescences. concentrations sums shown to substantially higher than Lublin. Similarly, allergies is study site Ukraine. results indicate that presence grains may associated long-distance transport. non-glandular glandular was found examined organs. inflorescences covered two (short long) (linear biseriate), whose secretory product cause dermatitis sensitive subjects upon
