Summary The relationship between the fluorescent intensity of individual soybeanGlycine max (L.) Merr.} roots or root segments and their nutrient absorption capacity or elongation rate was investigated. Data are reported for the short-term (30 sec) absorption of rubidium, phosphate, and iron by roots of soybean plants which had been cultured in a soil solution system. Results indicate that the rates of absorption of Fe, was directly related to the fluorescent intensity, with the most rapid absorption per unit of root length or surface area occuring in regions of most intense fluorescence. Elongation rate was positively correlated to the intensity of root fluorescence. These relationships should be useful for estimating root elongation rates in soil systems and for evaluating the distribution of growth rates and nutrient absorption activities within a crop root system.
