Fig. 2

Root elongation and shoot extension of the seedlings after a 7-day exposure of 50 μM Cd (Cd treated) for the rice cultivars, TY3, TK9, TNG71, KH145, TKW1, TKW3, TCS10, and TCS17, and making comparison with a check (CK) for root elongation and shoot extension. Error bars represent the standard errors of the mean values (replicates n = 3). Same lowercase letters above the black bars and same capital letters above the gray bars indicate the mean values are not significantly different at p < 0.05 among the cultivars according to the last significant difference (LSD). *, **, and *** indicate significant differences at p < 0.05, p < 0.01, and p < 0.001 between Cd treated and CK by the t-test
