Proline (pro) can accumulate in plant leaves through environmental stress and may be a potential marker of ozone pollution. Biochemical extraction and quantification of needle soluble pro for white pine at Coweeta indicate that soluble pro is of sufficient magnitude that could prove useful as a bioassay for ozone monitoring. The application of SEM of stomated topography and extraction as an aid to further interpret ozone effects is illustrated.</style></abstract><accession-num><style face="normal" font="default" size="100%">LTER.1989-80905</style></accession-num></record></records></xml>
