Methods for Testing the Contribution of Brace Roots to Anchorage. The measure of plant biomechanics with all brace roots intact is labeled "A." For brace root removal experiments, the excision of sequential whorls starting at the top are labeled alphabetically. Here is an example of a plant with three whorls of brace roots, with two that enter the soil. The uppermost whorl of brace roots that enter the soil is excised and the measurement is labeled "B." The next whorl of brace roots that enter the soil is then excised and the measurement is labeled "C"
