Abstract
In this paper, we describe the influence of monocarboxylic acids (formic acid and acetic acid) and dicarboxylic acids (succinic acid and adipic acid), which are usually contained in aerosol particles and fog water, on the growth of tobacco plant. Their influence was examined by spraying the acid solutions on intact plants and by administering them in a culture medium for suspension-cultured cells. Their growth rates suggest that the influence of short-chain monocarboxylic acids was not significant in both the intact plant experiment and the cell culture experiment. In contrast, dicarboxylic acids exhibited significant influence on the growth of intact plants and no influence on culture cells, indicating that their toxicity is exerted mainly on the tissue of leaf surface. Phytotoxicity of dicarboxylic acids is higher than that of monocarboxylic acids.
