Abstract
(4) The cadmium is highly toxic and for all biota in very small concentrations, these study was to know the limit of
phitotoxicity and nutrition of cadmium in bean cultivars variety black Jamapa, and to measure absorption of cadmium in
roots, stem, leaves and grain. The experiment was carried out in plots with bean of the black variety Jamapa, in
greenhouse, 6 treatments in the water of irrigation with 0, 25, 50, 100 y 200 micromoles of cadmium, to quantification of
cadmium in plant, is carried out with ICP previous acid digest (I) method D4638-86 of ASTM 1990. Was carried out
analysis of variation and results indicate that, there were been significant for the variables : number of leaves, foliate
area,
dry weight from root, height of plant; the threshold of toxicity for the plant in the condition that it was carried out the
experiment were 100 - 200 micromoles of cadmium applied in water of irrigation weekly, the visual symptom were: yellow
of leaves, morphologic changes in leaves showed leaves bi-foliate and tetra-foliate in treatments upper of 100 micromoles
of cadmium.
