  1. Transformation frequencies in marker-free transformations (MF) are derived from the number of transformed shoots (transformed) and the total number of shoots minus the number of transformed shoots (non-transformed). Transformation frequencies in marker-assisted transformations (MA) are derived from the number of rooting shoots (transformed) and the number of explants used minus the number of rooting shoots (non-transformed).
  2. *null hypothesis: group 1 equals group 2.
