Abstract
A rootbox is described which allows observation of an intact, entire root system. Roots are sandwiched against a plexiglass surface by a nylon mesh that is impermeable to roots, but permeable to water and nutrients. To quantify root growth non-destructively, roots of different size classes are traced onto acetate sheets using different color pens, and root lengths determined by digital image analysis.
