With Nicotiana rustica L., a noncommercial tobacco, plants receiving an optimum nitrogen supply were found to be more susceptible to ozone injury than those receiving deficient or luxury supplies. Furthermore, it was found on analyses of the third oldest tobacco leaf that, while these optimum plants showed little or no increase in respiration as a result of ozone in concentrations too low to produce visible injury, plants grown with deficient or excess nitrogen showed a significant increase in respiration under these same conditions. The increase in respiration was accompanied by a comparable and equally significant decrease in carbohydrate content in the latter plants which was not apparent in plants at the optimum nitrogen supply, as well as an increase in total nitrogen, protein-nitrogen, and amino-acid nitrogen. It is suggested that the carbohydrate reserve built up in plants grown with deficient nitrogen nutrition serves as protection against the oxidative potential of ozone. Likewise, a decrease in carbohydrate content below that of optimum plants provides protection in plants grown with an overabundance of nitrogen fertilization, though possibly by a more complex mechanism. 20 references, 7 figures, 2 tables.
