Analysis of airborne pollen grains in Denizli

Airborne pollen distribution in Denizli Province was measured volumetrically during 2 consecutive years, 2005 and 2006, on a weekly basis. A total of 11,981 pollen grains/m3 belonging to 42 taxa were determined. In 2005 the total was 5368 pollen grains/m3 and in 2006 it was 6613 pollen grains/m3. | Turkish Journal of Botany Turk J Bot (2013) 37: 74-84 © TÜBİTAK doi:10.3906/bot-1201-4 http://journals.tubitak.gov.tr/botany/ Research Article Analysis of airborne pollen grains in Denizli 1, 2 3 1 Aykut GÜVENSEN *, Ali ÇELİK , Bülent TOPUZ , Münir ÖZTÜRK Botany Department, Science Faculty, Ege University, Bornova, İzmir, Turkey 2 Biology Department, Faculty of Science & Arts, Pamukkale University, Denizli, Turkey 3 Department of Otolaryngology, School of Medicine, Pamukkale University, Denizli, Turkey 1 Received: 04.01.2012 Accepted: 23.07.2012 Published Online: 26.12.2012 Printed: 22.01.2013 Abstract: Airborne pollen distribution in Denizli Province was measured volumetrically during 2 consecutive years, 2005 and 2006, on a weekly basis. A total of 11,981 pollen grains/m3 belonging to 42 taxa were determined. In 2005 the total was 5368 pollen grains/m3 and in 2006 it was 6613 pollen grains/m3. Among the taxa recorded, 26 belonged to arboreal and 16 to nonarboreal taxa. At the end of the 2 years total pollen counts comprised 79.68% arboreal, 19.48% nonarboreal, and 0.84% unidentified taxa. The number of pollen grains/m3 among arboreal plants was as follows: Pinaceae (24.19%), Cupressaceae/Taxodiaceae (15.99%), Olea europaea (11.35%), Quercus spp. (6.08%), Platanus orientalis (5.68%), Acer spp. (2.93%), Morus spp. (2.58%), Salix spp. (1.59%), and Eucalyptus camaldulensis (1.47%), and for nonarboreal representatives: Poaceae (6.63%), Asteraceae (3.08%), Chenopodiaceae/Amaranthaceae (2.27%), Plantago spp. (2.12%), Urticaceae (1.82%,) and Xanthium strumarium (1.52%). The distribution of pollen in the atmosphere of Denizli was highest in May, followed by June, April, and March. Key words: Aeropalynology, pollen calendar, allergy, Denizli, Turkey 1. Introduction The release of large amounts of pollen grains in the atmosphere by the male reproductive units of plants for the purpose of pollination is a natural phenomenon. However, during this release pollen
