Table 4 Influences of NaCl stress and T. viride on seedling height stress index (%) (SHSI) and the water status of tomato seedlings

Treatments	Seedling height stress index (%) (SHSI)	Seedling water status
Treatments	Seedling height stress index (%) (SHSI)	Water content (%) (WC)	Relative water content (%) (RWC)	Water saturation deficit (%) (WSD)
T₀	–	92.71 ± 4.906a	91.56 ± 4.845ab	8.44 ± 0.446d
T₁	–	93.31 ± 4.937a	96.54 ± 5.108a	3.46 ± 0.183e
T₂	36.69	89.49 ± 4.735a	85.16 ± 4.526ab	14.84 ± 0.785b
T₃	58.98	91.53 ± 4.843a	87.64 ± 4.638ab	12.36 ± 0.634c
T₄	24.94	88.61 ± 4.688a	79.85 ± 4.225b	20.15 ± 1.066a
T₅	45.55	93.66 ± 4.956a	84.58 ± 4.476ab	15.42 ± 0.816b

T₀, T₂ and T₄ represent tomato seedlings grown on MS medium under 0, 50 and 100 mM NaCl stress, while T₁, T₃ and T₅ represent tomato seedlings grown on MS medium with T. viride under 0, 50 and 100 mM NaCl stress
