t0“tomato (Solanum lycopersicum) and eggplant (Solanum melongena)”
e1“as Pb concentration increased from 0 to 5.0 ppm, the germination percentage, plumule and radicle length, fresh and dry weight decreased in tomato from 94 to 19%, 6.78 to 0.88 cm, 5.77 to 1.16 cm, 0.49 to 0.10 mg and 0.05 to 0.01 mg, respectively, while in eggplant, the decrease in the corresponding parameters was from 93 to 20%, 5.76 to 1.23 cm, 5.20 to 1.89 cm, 0.46 to 0.11 mg and 0.05 to 0.01 mg”
