Abstract
Sedimentation of pollen particles of four species of anemophilic plants (white poplar, hybrid willow, tolocanocular poplar, and Chinese miscanthus) growing in CSBS SB RAS is studied. 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. Sedimentation rates are determined for individual pollen grains of these plant species and their clusters of two to six pollen grains. Dependence of the cluster sedimentation rate on the number of pollen grains in a cluster is derived.
