  1. Values of root and shoot lengths are presented as mean of three experiments ± SD
  2. Root and shoot lengths of seeds grown in TPM dyes are significantly different from that of plants grown in sterile distilled water by **p < 0.01, Root and shoot lengths of seeds grown in biodegraded products of TPM dyes are significantly different from that of plants grown in TPM dyes by *p < 0.05
