  1. 1Values are means of measurements made 6 and 15 months (M6 and M15, respectively) after planting, unless otherwise indicated
  2. 2The rate of trunk diameter increase between month 0 and 15, namely (TD15-TD0)/TD0, and trunk diameter at month 0 used as a covariate
  3. 3The rate of net height increase between month 0 and 8, namely (NH8-NH0)/NH0
  4. 4The rootstock trunk girth at month 15 was used as a covariate
  5. 5Significance was for branch length when the number of branches was used as a covariate
  6. 6Treatments with the different low case letters differed significantly at P = 0.05 based on the nest-model comparisons
