Abstract

A method is described to quantitatively record the upward force of an emerging seedling that exhibits epigeal germination. A soybean [Glycine max (L.) Merr.] seedling showed an average maximum emergence thrust of 434 g at 8 to 10 days after planting. Herbicides can be grouped into those that inhibit, have no effect, or stimulate the upward thrust exerted by an emerging soybean seedling. At the rates studied, the herbicide 4-amino-3,5,6-trichloropicolinic acid (picloram) showed the greatest inhibition and 3-amino-2,5-dichlorobenzoic acid (chloramben) the greatest stimulation of emergence force of soybean seedlings.
