Table 5 Controlled environment wax layer root penetration experiment, measures of root architecture at tillering. Average tiller number, number of roots (crown and seminal), dry weight of roots (total, above and below the wax layer), dry weight of shoots and root to shoot ratio.

  1. Data averaged across strong and weak wax layer strengths as there was no significant main effect of wax strength or interaction between wax strength and cultivar.
  2. 1Bt = back-transformed.
