Salt Absorption of Plants


Our earlier article directed the attention of the general reader to two independent series of investigations which have been in progress in different laboratories for several years. The combined investigations are extensive and deal with a variety of plant materials and environmental conditions. These apparently divergent investigations yield a consistent general picture of the process of salt uptake in plants, and we are not persuaded by Prof. Lundegårdh's arguments that this picture can be dismissed by the general reader. Our view is that salt accumulation involves vital processes in a more complex and intimate manner than would be suggested by Prof. Lundegårdh's discussion with its reference to principles expressed "in modern text-books of plant physiology" and "well-known terms of physical chemistry".
