- Abstract
The present article deals with the efficacy of seed hairs of poplar trees (Populus spp.) as a potent natural airborne pollen trap. Differenht species of Populus are commonly found planted along the streets in the cities of North China. The seed hairs and pericarp of poplar trees were collect6ed from the trees and on the ground in Beijing Botanical Garden of Chinese Academy of Sciences and around Miyun Reservoir during May 2005 for pollen analysis. Different pollen spectra are recorded from different smples and are characterised by dominant occurrence of pollen grains of pollen grains of arboreal and anemophilous plants. In addition, pollen grains of non-arboreal plants including grasses are also found trapped. Among the 46 trapped pollen grains, 26 are known to be allergenic. This study suggests that poplar seed hairs possibly make people feel uncomfortable due to the presence of allergenic pollen traped in the hairs.
