Figure Lengend Snippet: Effect of 80 mg·L –1 of organic carbon from HA, SB (HO* scavenger), and TIRON (O 2 •– scavenger) on root and shoot development. Rice plants grown for 72 h in nutrient solution with HA and addition of SB (3 mM L –1 ) or TIRON (800 μM L –1 ). (a–e) Root and shoot biomass, and root morphology of rice plants during exposure to HA and SB. (f–j) Root and shoot biomass, and root morphology of rice plants during exposure to HA and TIRON. The analysis of root morphology was carried out using WinRhizo Arabidopsis software. SB: sodium benzoate. HO*: hydroxyl radical. TIRON: 4,5-dihydroxy-1,3-benzene disulfonic acid. O 2 •– : superoxide anion. HA: humic acid. DW (g): dry weight in grams. LR: lateral root. Chem: a chemical substance added to solution as an scavenger. Bars indicate the four biological replicates standard error. Different letters above the bars represent significant differences according to Tukey’s test ( p -value ≤ 0.05).
Article Snippet: The images were analyzed using the WinRhizo Arabidopsis scanner-based image analysis system software (Regent Instruments, Montreal, QC, Canada, 2012b) at a setting of 600 dpi (dots per inch).
