SEASONAL DYNAMICS OF AMARANTHACEAE (AMARANTHUS AND CHENOPODIUM) POLLEN IN THE ATMOSPHERE OF ANDIJAN AND ITS RELATIONSHIP WITH METEOROLOGICAL FACTORS

The seasonal dynamics of Amaranthaceae (Amaranthus and Chenopodium) pollen in the atmospheric air of Andijan wereinvestigated during the spring, summer, and autumn seasons of 2025. Aerobiological monitoring was carried out using thevolumetric method. The total pollen concentration reached 71.315 grains/m³, with the highest values recorded in August–September. Spearman correlation analysis revealed a statistically significant negative relationship (p < 0.05) between pollenconcentration and relative humidity as well as precipitation, whereas no significant relationship was found with temperature andwind speed. The obtained results indicate that humidity and precipitation act as limiting factors in the dispersion ofAmaranthaceae (Amaranthus and Chenopodium) pollen.
