Silver maple seedlings were fumigated for 12 h per day for 30 days with either 25 pphM O/sub 3/, 50 pphM SO/sub 2/, or both. Leaf length was measured three times a week throughout the study. At the end of the treatment period, leaf length, leaf width, leaf area and leaf dry weight were measured. Fumigation with SO/sub 2/, O/sub 3/, or both gases tended to retard leaf initiation, while fumigation with O/sub 3/ and O/sub 3/ plus SO/sub 2/ markedly reduced leaf length, width, area, and dry weight. Leaf shape and the leaf weight area ratio were not affected by fumigation. The reduction in leaf size of photosynthetic area caused by air pollutants may reduce the amount of photosynthate available for plant growth and result in slower growth of the entire plant.
