The experiment was laid out in a completely randomized block
design. Experimental treatments consisted of factorial combinations
of two factors: mycorrhization (−AM and +AM) and salinity
(S1 and S2). Each of four treatments had eight replicates and was
repeated for each rootstock leading to a total of 32 pots per rootstock.
The pots position was changed every week for eliminating
the environmental error. The seedlings were harvested 45 days
after NaCl treatments.
