Resumen:
Heavy metal pollution of agricultural soils constitutes a threat to crop growth and may impair yields and food security since international reference values could be exceeded. Cadmium (Cd) is one of the most relevant heavy metal due to its toxicity and plant availability. The aim of this study was to screen two soybeans varieties (ES Mentor, a low Cd accumulative variety, and Primus, a high accumulative variety) on different European mine wastes with a different combination of heavy metals. The mine wastes were mixed with a standard growth substrate at different dilutions to minimize potential effects of differences in soil structure and pH. The substrate from a zinc mine resulted in a strong inhibition of the germination and growth in both varieties probably due to its high arsenic concentrations. On the other hand, plants grown on substrate mixtures from a copper mine performed equally well or better than those of the control.  Common responses were a higher leaf greenness (SPAD) and a reduced specific leaf area, indicating a decrease in the size of the leaves and more compact tissues. Interactions between morphological parameters and the quality of the soils as well as the differences in cultivar performance will be discussed.@font-face { font-family: "Times New Roman";}@font-face { font-family: "宋体";}@font-face { font-family: "Liberation Serif";}@font-face { font-family: "AR PL SungtiL GB";}@font-face { font-family: "FreeSans";}@font-face { font-family: "Arial";}p.MsoNormal { margin: 0pt 0pt 0.0001pt; text-align: left; vertical-align: baseline; font-family: "Liberation Serif"; }span.msoIns { text-decoration: underline; color: blue; }span.msoDel { text-decoration: line-through; color: red; }div.Section0 { }
