Effect of soil aeration on root morphology and photosynthetic characteristics of potted tomato plants (Solanum lycopersicum) at different NaCl salinity levels

Table 2 total root length, surface area, volume and forks of potted single tomato plants measured at mature period (155 DAT) for the 4 aeration levels at the 3 NaCl stress levels

Note: Values followed by different small letters in the same column meant significant differences at p < 5%. ANOVA F-value for main and interaction effects were not significant (ns) or significant at ≤5% (*) and ≤ 1% level (**).Under the S₃A₀ treatment plants all died, So the S₃A₀ row is empty. Multiple comparison can’t be performed for S₃A₁ treatment because only 1 plant survived
