Flowering phenology and pollen production in different microclimatic conditions of a city and their influence on Betula spp. and Artemisia spp. pollen season pattern in Poznań

Paweł Bogawski

Abstract

Flowering phenology and pollen production of allergenic plants, Betula pendula and Artemisia vulgaris were analyzed in the context of microclimatic diversity of a city and its surroundings in years 2012-2013 in Poznań. Also, the relationship between the potential pollen emission of B. pendula, A. vulgaris, A. absinthium, A. campestris from a study area and the pollen concentration at the trap level was investigated. Following data have been used: air temperature from 7 city stations, Landsat and MODIS data, phenological, pollen production and population density data from field observations, airborne pollen concentration at two sites as well as land-use data. Taking into consideration the MODIS data, the mean intensity of surface urban heat island in Poznań reached 6-10°C in study period. Flowering in the city center began, on average, 1.4 – 4.7 days before the flowering in the outskirts for B. pendula. A significant negative relationship has been revealed between the timing of flowering and land surface temperature as well as road surface. Phenological maps and models have been developed as well. Three Artemisia species showed stable phenological order: A. vulgaris flowered as first, then A. absinthium and A. campestris. A. vulgaris was responsible for the majority of pollen emitted in study area, but A. campestris was also an important pollen contributor. Also, a method for estimating pollen emission from particular area was proposed.
