  1. a FD fractal dimension, Log(FA) fractal abundance, RA root angle, SD stalk diameter. Plot means (N = 72, 387, 30) were used to obtain the values for the 12 “Parents”, 66 “F1 hybrids”, and 5 “Check hybrids” entries.
  2. bOnly data for the five checks present for both environments were included in calculations.
