Plants of 72 varieties representing five small grain species were exposed to ozone concentrations ranging from 0.05 to 0.34 ppM. In descending order of susceptibility to ozone damage, the plants were hexaploid oats, diploid oats, rye, wheat, and barley. Varietal differences within the species in sensitivity were noted for both oats and rye. Symptoms of injury ranged from a faint discoloration at the leaf tip to complete leaf burn. Large scald spots frequently occurred in oats, usually starting where there was a bend in the leaf. Plants were injured at all stages of plant development, although they appeared slightly more sensitive at the three-leaf and boot stages of plant development than at more intermediate stages. 8 references, 3 figures, 1 table.
