| Abstract/Contents: | SUMMARY: An experiment was done to investigate the performance of plants (Lolium perenne (L.)) grown in roadside soil in the absence of roadside atmopheric conditions. Significantly fewer plants germinated in soil taken 0.6 m from the carriageway compared with soil taken 0.6 m from the carriageway. When plant populations were equal, plants grown in soil taken from deside the carriageway attained significantly greater dry weight and a significantly greater soluble nitrogen content. Aphids (Rhopalosiphum padi (L.)) on the plants grew more rapidly and had greater fecundity on plants grown in soil taken beside the carriageway. NO(x), absorbed by roadside soil, was probably the cause of these effects. the effects may also have been related to the greater de-icing salt concentration in roadside soil. An experiment with different concentrations of NaCl showed no effect on dry weight of L. perenne foliage or on any life-history parameter of R. padi. However, salt may play a role in the absorption of NO(x) by soils, its subsequent oxidation and hence its availability to plants. |
