Fig. 5From: Effect of soil aeration on root morphology and photosynthetic characteristics of potted tomato plants (Solanum lycopersicum) at different NaCl salinity levelsSketch map of potted tomato plants at different NaCl stress and soil aeration levels. Notes: A0, A1, A2, and A3 represent aeration volume are non-aeration, 2.3, 4.6 and 7.0 L/pot, respectively. S1, S2 and S3 represent light, moderate and heavy NaCl stress, respectively. No NaCl stress with non-aeration served as control and was identified by the designation CKBack to article page
