Abstract

A study was made of the sedimentation of the pollen particulates of Siberian silver fir, ash maple, corn, manchzhursky nutwood, sea-buckthorn. It is shown that the dispersion of the pollen of these six species provides a considerable number of agglomerates of two or more grains, composing from 33.3 to 44.8% of the resulting particles. In this case, these agglomerates contain from 60.4 to 72.3% of the pollen dispersed. The sedimentation rate of the agglomerates, including from 1 to 6 pollen grains, was determined. The dependence of the agglomerate sedimentation rate on the number of the pollen grains included was established.
