  1. Notes.
  2. -Values are Least Square Means from ANOVA ± standard errors (n = 6) at 35 days after transplanting.
  3. -Means within a column followed by the same letter are not significantly different at α = 0.05. A mean value with multiple letters indicates that it is not significantly different at α = 0.05 from multiple other genotypes as indicated.
  4. -(*) significant at α = 0.05, (**) significant at α = 0.01, NS = Not Significant.
  5. -(#) = number, TRL = total root length, R/S = root to shoot biomass ratio, SRL = specific root length.
