  1. aControl, the seeds without fungal inoculation
  2. bGermination percentages (mean ± SE, n = 3) within columns marked by different letters are significantly different at P < 0.05 (Fisher’s protected least significant difference test)
  3. cGermination was defined as emergence of the embryo from the seed coat (stage 2)
