Entire trees were enclosed in plastic covered greenhouses and were supplied various fractions of the atmosphere to find out whether ozone, peroxyacetyl nitrate, or fluorides were causing noticed deleterious effects. Results showed that the photochemical smog complex reduced the rate of water use by lemon trees, and also reduced photosynthesis. Continuous exposure of orange trees to 0.5 and 1.0 ppm of nitrogen dioxide caused severe defoliation and leaf chlorosis. The growth of young trees was reduced by PAN. Fruit production by grapes was reduced by smog exposure.
