Abstract
Growth in height of various species and seedlots of Platanus in ambient greenhouse air averaged only 75% of that in a carbon-filtered atmosphere. Variation in growth response among and within seedlots indicated that selection for pollution tolerant individuals is feasible. Variation in susceptibility to leaf injury was exhibited by plants fumigated with ozone and sulfur dioxide. American elm seedlings were more tolerant of both fumigants than Platanus, and differences in tolerance among progenies were apparent. 2 tables.
