Young navel orange trees and branches of a mature tree were enclosed and exposed for two years at Riverside, California, to activated carbon-filtered air, carbon-filtered air plus ambient levels of peroxyacetyl nitrate (PAN), or ambient air. The growth of the young trees was reduced by the addition of synthetic PAN at levels in ambient air. Leaf drop increased. With enclosed branches, significantly less growth occurred with PAN. Trends toward reduced yield of mature fruit were seen. Short-term apparent photosynthesis was not affected by fumigating a young tree with 20-80 ppb of PAN. 16 references, 5 tables.
