Ozone effects stomatal closure, but injury to the palisade cells in soybean (Glycine max L.) cotyledons also occurs. The visible and anatomical injury resembles that on other leaves. Cotyledons and primary leaves were most sensitive to ozone 6 to 7 and 13 to 14 days after seeding, respectively. The upper epidermis and 3 to 4 layers of palisade cells can be easily separated from the remaining tissue, thereby providing a good source of plant material to study the chemical nature of air pollution injury to stomata and to palisade cells. Extent of injury on cotyledons and primary leaves of each variety was similar; thus, the use of cotyledons to study the relative sensitivity of plant varieties to ozone is proposed. 11 references, 8 figures, 1 table.
