A Technique for the Measurement of Lead Tolerance in Plants

Abstract

BRADSHAW reported1 that root growth was inhibited when plants of Agrostis tenuis were grown in soil from the tip of an old Welsh lead mine, while plants originally growing on the tip produced normal roots. This suggested that some plants of A. tenuis were inherently more tolerant of the lead and zinc in the soil than others. On similar waste tips in Scotland, A. tenuis is replaced by Festuca ovina and Deschampsia flexuosa, and a method has been worked out for the measurement of lead tolerance in F. ovina from soils of different lead contents.
