Soybean--Growth; Roots (Botany)


A procedure for estimating the total root length, root surface, and root hair surface is described for greenhouse-grown soybeans. Data are presented on the extent of the root systems of 3-week and 14-week old soybeans. The possibility of correlating data from greenhouse-grown soybeans with that of field-grown soybeans as a method to make some predictions on extent of the root systems of field-grown soybeans is suggested.
