Cadmium was transported through the special carrier system into the cells of cotyledons, hypocotyls, and roots spring radish young plants. The transport of cadmium was inhibited by metabolic inhibitor, like DNP. The <TEX>$K_m$</TEX> values for cadmium were 0.7 ppm for cotyledons, 1.72 ppm for hypocotyls, and 0.3 ppm for roots, and <TEX>$V_{max}$</TEX> for cadmium was <TEX>$40ppm{\cdot}h^{-1}{\cdot}g{\cdot}fresh\;weight^{-1}$</TEX> for cotyledons, <TEX>$313ppm{\cdot}h^{-1}{\cdot}g{\cdot}fresh\;weight^{-1}$</TEX> for hypocotyls, and <TEX>$606ppm{\cdot}h^{-1}{\cdot}g{\cdot}fresh\;weight^{-1}$</TEX> for roots. Cadmium cannot prove to be inducer for proline accumulation. Therefore, proline accumulation cannot be used as a marker to test the level of heavy metal pollution.
