D1: seedlings inoculated with the D1 strain of D. antarctica.
D2: seedlings inoculated with the D2 strain of D. antarctica.
SL/RL: stem length/root length.
DRC/SL: diameter at root collar /stem length.
SDW/RDW: stem dry weight/root dry weight.
The values correspond to the mean of n = 60 seedlings per treatment.
Values with different letters in the column differ significantly from one another (Tukey-HSD test p ≤ 0.05).
