The work was performed in hydroponics with four acetate doses. The experimental design was random blocks with three replications on a factorial scheme. The variables root (RL) and shoot (SL) length, number of roots (NR), and root (RDM) and shoot (SDM) dry matter were measured. Analyses of variance, relative performance, and regression adjustments were used. Only the dose 6 genotype interaction effect for SL, NR, and SDM were not significant. Among the variables analyzed, RL was influenced the most by the acetate treatments. The regressions established for this variable revealed 6 tolerant and 19 sensitive genotypes. Most of the tolerant genotypes were irrigated japonica.  aabiotic stress  aOryza Sativa  aOrganic acids  aPlant toxicity1 aLUZ, V. K. da1 aMAIA, L. C. da1 aCARVALHO, F. I. F. de1 aOLIVEIRA, A.
