‎---- PREMIERE EDITION FRANCAISE ---- BEL EXEMPLAIRE ---- "A REFERENCE WORK". (DSB) ---- "Pfeffer's comprehensive Pflanzenphysiologie became a well-known reference work. It presented not only a mine of information but also a view of Pfeffer's aims and philosophy as a physiologist studying fundamental life processes with plants as his subjects... Many of Pfeffer's investigations were basic to plant physiology. His work on the role of asparagine was controversial but nevertheless an advance in the study of plant metabolism when viewed in a historical context. He made extensive contributions to the study of irritability in plants by investigating the movements of leaves, the opening and closing of flowers, the influences of variations of light and of temperature, the effects of tactile stimuli and the physiology of transmission in irritability phenomena. He also studied the sleep movements of plants. Using aniline dyes, he pioneered the method of vital staining and followed the assimilation and accumulation of various dyes within the living cell...".
