a
Radicle and plumule lengths of seeds grown in the original dye are significantly different from those of seeds grown in distilled water by P < 0.001.
b
Radicle and plumule lengths of seeds grown in degraded products are significantly different from those of seeds grown in distilled water by P < 0.001.
c
Radicle and plumule lengths of seeds grown in degraded products are significantly different from those of seeds grown in original dye water by P < 0.001
d
Data are represented as the mean from three sets of experiments ± standard error. Results were analyzed using one-way analysis of variance (ANOVA) with the Tukey–Kramer multiple comparison test.
