Abstract

Twenty-two soybean germplasm lines were grown in 1/5 Steinberg solution containing 6 ppm Al in 41 pots at pH 4.4 during the 1985 growing season to evaluate their tolerance to acidity and aluminum stresses. Plants were grown in three replications and separated on the basis of relative root lengths ratios (RRL = root length [cm) of plants grown in 6 ppm Al divided by root length [cm] of plants grown without Al). The system of classification was RR1 >100% = highly tolerant; 85-99% = tolerant; 74-84% = sensitive; and <74% = highly sensitive.
