The timing and amount of stem damage and bud kill, along with the Cl content of twigs, were observed over one or two winters in Fraxinus pennsylvanica Marsh, Cornus stolonifera Michx, Malus sp. cv. Hopa, Salix pentandra L., and Syringa vulgaris L. growing along Minnesota highways. Depending on species and the year, damage occurred between January and May.Cold hardiness was compared for highway- and garden-grown Syringa vulgaris L. and Fraxinus pennsylvanica Marsh. Hardiness was assessed as percentage of xylem and cambial browning and percentage of bud kill after exposure to test temperatures between −45 and +4 °C. In November, hardiness was the same, but from mid-December into March, highway twigs showed more damage than garden twigs at the same test temperatures. The differences between highway and garden twigs coincided in time with differences in twig Cl.

A study is made on the sedimentation of pollen particles of the anemophilous plants of six species (Salix caprea L., Salix pentandra L., Betula davurica Pall., Plantago media L., Chenopodium album L.,Artemisia sieversiana Willd.), growing in the CSBG SB RAS. These species are widely represented in the biocenosis of the Russian Federation and are the producers of substantial amounts of allergenic pollen which can be carried by winds over great territories. It is shown that there is a considerable number of clusters that contain two and more pollen grains. Sedimentation rates are determined of both the individual pollen grains of these plants and their clusters with 2-6 pollen grains. It has been established that the sedimentation rate of clusters depends on the number of the pollen grains contained.
