  1. One-way analysis of variance was carried out for each parameter studied. Tukey’s post hoc multiple mean comparison test was used to test for significant differences between treatments (at p ≤ 0.05%). Univariate analysis was used to test significant differences in treatments, accessions and their interaction for an individual parameter. All statistical analyses were performed with IBM.SPSS statistics, Version 19.The results of each experiment (biochemical essays) were repeated three times and (20 times for mycorrhizal intensity essays)
  2. The values are the average of 3 determinations, and the values followed by different letters are significantly different (p ≤ 0.05)
