Table S4: Percent Relative Net Root Growth (RNRG) means and standard errors of the means for sorghum accessions subjected to {27} µM Al3+, {37} µM Al3+ and {58} µM Al3+ in nutrient solution. Values are the means of three replications for the Al activity of {27} µM Al3+ and two replications for the other Al activities. Seven plants per replication were used for all Al treatments. Accessions whose RNRG means are followed by the same lower-case letters within each of the 3 Al activities constitute homogeneous RNRG groups by the Scott-Knott test (P<0.05)
