Table 2 Comparative measurements of the length and density of first and second order lateral roots per crown root segment

From: The effect of altered dosage of a mutant allele of Teosinte branched 1 (tb1-ref) on the root system of modern maize

   Per crown root segment Per unit of crown root length (cm) Per unit of 1storder LR
   LR total length LR number LR total length LR number LR average length LR number

  1. Notes
  2. -Values are least square means from ANOVA ± standard errors (n = 12) 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. -LR = lateral root, WT = wild type, # = number.
