Summary

The respiration quotient (R Q) of the tobacco leaves is always higher than one. In contrast to that of the leaves of succulent plants it does not drop below unity during the night. From this it is concluded that the organic acids (malic, oxalic and citric acids), which serve as respiration substrate, cannot be related to the carbohydrate metabolism (tricarbon acid cycle). They must rather be considered as primary assimilation products or as related to the nitrogen metabolism (transamination of the primary assimilation product aspartic acid).
