Abstract
The settling of pollen particles of four species of anemophilic plants ( Populus alba L., Salix hybrida , Miscanthus sinensis Andersson, Chosenia arbutifolia (Pall.) A. K. Skvortsov) growing in the exposition of the CSBS SB RAS was investigated. These species are widely used in landscaping cities of the Novosibirsk region and are producers of impressive amounts of allergenic pollen, which can be carried by the wind over significant distances. The presence of a significant proportion of clusters, which include two or more pollen grains, is shown. Settling rates were determined as individual pollen grains of these plant species and their clusters, which included from two to six pollen grains. Dependence of cluster sedimentation rate on number of pollen grains included in it is established.
