Excerpt from The Translocation of Solutes in Plants: A Critical Consideration of Evidence Bearing Upon Solute Movement If one reads the literature dealing with problems relating to the translocation of solutes within plants, it soon becomes apparent that, relative to the importance of the subject, very little experimental evidence is available to which one can confidently turn for information and guidance. In fact, the available evidence has led to atly contradictory conclusions. These contradictions Obtain even with refer ence to such fundamental points as the tissues chie y concerned in transport, and the mechanism Of transport. One or both of these questions must be solved before any real progress can be made in an understanding of solute movement, or of the factors in uencing the direction of movement, the rate of movement, or the final distribution of the materials. Any satisfactory explanation of the behavior of those plants which are differentiated into tissues and organs having differences in abilities to produce or absorb special substances, as for example differentiation into leaves which carry on photosynthesis and roots which absorb soil solutes or water, must involve also an explana tion of conditions determining translocation of solutes from one part to another, because interchange of special solutes or their distribution within an organism has a profound effect upon its behavior. NO higher plant could have developed or could even continue to exist without an effective conducting tissue and transport mechanism.
