Abstract
We have measured the sedimentation rates of the pollen particles of several species of anemogamous plants (including those introduced by a man) growing in Western Siberia (pine trees: ordinary, Siberian, mountain, Crimean; inoculum hemp, rib grass). It is shown that upon spraying, the anemophilous pollen particles are represented by both single pollen grains and agglomerates of two or more grains. The portion of agglomerates in the total number of particles deposited is estimated. The sedimentation rates of the pollen particles are determined. The sedimentation rates of the pollen agglomerates of one or more grains are measured. The dependence of the sedimentation rate on the number of grains in an agglomerate is established.
