Print on Demand. This book explores the intriguing phenomena of acidity fluctuation and respiratory activity in cacti and other succulents. The author reviews the extensive research on these plants since the 19th century, which has shown that the respiratory quotient—the ratio of carbon dioxide output to oxygen intake—in succulents is lower than unity, an anomaly primarily attributed to the accumulation of malic acid. The book examines the various theories proposed to explain this unusual acid-based respiratory metabolism, including the impact of environmental factors like light on acid formation and degeneration and the role of the acids in photosynthesis. The author also delves into the historical context of these investigations, providing insights into the evolution of our understanding of plant physiology. Through its detailed analysis, this book enriches our understanding of the unique physiological adaptations of succulents and the significance of these adaptations in their survival and ecological roles. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book.…

That the respiratory activity, or rather the phenomena connected with the evolution of carbon dioxide, in cacti and in other succulents is peculiar and that the acidity of the juices of these plants exhibits periodic rise and fall have been known for a long time. These phenomena have been the subject of a considerable number of researches, some of which have been elaborate and thorough.
Within the last 25 years there have been published the comprehensive papers of Aubert and of Astruc dealing directly with the problems of the physiology of the succulents, in which may be found a survey of the literature. These accounts, with the excellent review of the subject that can be found in Czapek's Biochemie der Pflanzen, as well as the short but well-digested treatment given by Spoehr, perhaps make it unnecessary to go into great detail, nevertheless it will be well for the sake of convenience to summarize the present state of knowledge concerning the points mentioned above.
The two principal phenomena with which we are concerned, namely, the acidity with its periodicity and the carbon dioxide-oxygen quotient, are, as is now known, intimately connected; but in the earlier literature they were not associated.
It was that remarkably astute investigator, de Saussure, who first discovered that in a certain cactus form (Opuntia sp.), with which he experimented, the intake of oxygen might, under some circumstances, greatly exceed the output of carbon dioxide. In consequence of this the so-called respiratory quotient, instead of approaching unity, fell far below it. But at that time there was no knowledge of the acidity of the plant juices, let alone its periodicity, so that the significance of this peculiarity was not understood. As to the acidity of succulent plants, we owe the first mention to a casual observation by Benjamin Heyne in 1819, who contributed a note regarding the more acid taste of the leaves of Bryophyllum (Cotyledon) calycinum in the morning than late in the afternoon.
