Response of the Germination of Bean (Vigna unguiculata L. (Walp) to the Toxic Effects of Heavy Metals


Objective: To evaluate the toxic effects of metals on the crop Beans (Vigna unguiculata L. (Walp). Materials and Methods: assays of seed germination, elongation of the root, growth of hypocotyl and radicle in these plants as biomonitoring parameters varying concentrations of metals. The metals selected for this study were Cd and Pb. Findings: The seeds of V. unguiculata were sensitive to the presence of metals in comparison to the behavior of plants witnesses, showing all the biomarkers evaluated sensitivity to Cd and Pb however did not complete blockade of the germination and initial growth of seedlings, being the effect more dramatic by the presence of cadmium than with lead, observing a maximum values in the germination rate of 63 and 80%, respectively, in comparison with the control treatment, which were correlated with strongly to changes in morphology and anatomy of the seed. Application/Improvements: The Bean was able to survive and tolerate these polluting metals, so it could be used for the ecotoxicological monitoring of contaminated soils for future studies of phytoremediation.
