    Root—length estimates obtained using three different methods of a commercially available image analyzer were compared. Precision, accuracy, and the speed of obtaining estimates differed significantly among the Semirandom, Parallel, and Right Angle methods; this was a result of root orientation effects and analyzer calibration limitations. A new rapid, accurate, and precise method of obtaining root—length estimates using the analyzer was developed. The procedure interfaces the image analyzer with a microcomputer and used a program that standardizes orientation effects during calibration.
