Abstract
The use of deicing salts on roads and highways in northern states [USA] results in the accumulation of high salt levels in soils along such roads. Roadside populations of 2 herbaceous perennials, Agropyron trachycaulum and Solidago juncea show significantly greater tolerance to salt than control populations when grown under controlled conditions and watered with solutions varying in salt concentration. For Agropyron, plants from roadside sites showed greater biomass accumulation and less purple coloring on the leaves than control plants. For Solidago, roadside plants were better able to initiate new growth during the course of salt treatment experiment. In general, both species were quite salt tolerant.
