↵^z Percent of the five largest roots measured one cm inside indicated container size that deflected down or around at the 11, 57, or 170 L container size.
↵^y Means in a column within species with a different lower case letter are statistically different at P < 0.05; n = 5.
↵^x Means in a row within species with a different upper case letter are statistically different at P < 0.05; n = 5 using one way ANOVA for each retention time independently.
