Succinic Acid Content of the Cotton Plant.

Although succinic acid is known to be widely distributed in plant tissues there is only a limited amount of quantitative data on its occurrence. Studies which have been made of the changes in concentration of succinic acid during development of the tobacco plant indicate that it is to be regarded as one of the more active metabolites (4). In a previous study of the organic acids of the cotton plant (2) it developed that 14 to 50%o of the total organic acids in various tissues were reported, as is customary, as "unidentified acids," i.e., acids other than citric, malic and oxalic. This paper presents data on the concentration of succinic acid in the same or similar tissues.
