Description:   The metal tolerance of Agrostis scabra (tickle grass) populations from metal-contaminated and uncontaminated soils in the Sudbury Area was investigated.  Greenhouse clone-based root-growth experiments using Cu, Al and Ni treatments in acidic conditions showed that tolerance indicies were significantly higher in plants from contaminated sites.  Seed-based hydroponic growth experiments showed no significant differences in percent germination, while root growth was mostly greater for seeds from contaminated sites and leaf growth measurements were inconsistent.  Seed-based soil growth experiments showed that seeds from contaminated soils had greater tolerance indices when grown in contaminated soil and a 50:50 soil mixture (contaminated:uncontaminated).  It was concluded that Agrostis scabra grown on contaminated Sudbury soil is metal tolerant.
