The atmospheric reactions that are involved in the formation of photochemical oxidants are reviewed. The major phytotoxicants which are discussed are ozone and peroxyacetyl nitrate. The role of stomates in the exchange of atmospheric gases between the environment and the interior of the leaf is summarized. The opening and closing of stomates under various light conditions and the response of different age plants to ozone and peroxyacetyl nitrate was investigated. The response of different age plants to ozone and peroxyacetyl nitrate was investigated. The response of different age plants to peroxyacetyl nitrate and ozone suggested that the mechanism of damage from the two oxidants was different. Because of the light depenency for plant damage by peroxyacetyl nitrate, the effects of the oxidant on the photosynthetic reactions was investigated. The effect of ozone on carbohydrate metabolism and permeability in citrus leaves is presented.
