Асиметрія розподілу пилку анемофільних рослин

Abstract

It is very important to realize the regularity in changing of pollen concentration in the air for the preventive measures of seasonal allergic diseases. Patients and doctors are to be warned about seasonal changes to avoid the mass intensifying of pollen allergy. The purpose of the research was the determination of asymmetry of pollen distribution on each day during the period of flowering of anemophily plants as the result of which allergic reactions are prolonged. The research material was based on the information of the aerobiological monitoring in the town of Zaporozhye in the period from 2006 to 2010 by the example of ragweed, mulberry, birch, pine-tree and elm. The asymmetry was estimated as the dependence of central moment upon the third degree standard deviation in the third degree to the confidence interval in 95%. The distribution of pollen in time has positive asymmetry at the average of 0,9 ± 0,32. Ragweed’s pollen is distributed almost symmetrically on each day (0,28 ± 0,36). The distribution of elm’s pollen is the most asymmetric (1,27± 0,68). Since elm bears blossom before the appearance of leaves, it can cause the prolonged circulation of its pollen in the air in comparison with other kinds of plants. The study of green plants and their role in air cleansing of allergenic pollen is a promising and advanced direction in research.
