Abstract:
With the Trifolium repens as experimental materials,using the different concentrations of heavy metal Cd and Pb stress.To explore the Trifolium repens seed germination and seedling growth characteristics under the heavy metal Cd and Pb stress.Designed to the Trifolium repens for further studies on heavy metal contaminated soil repair function to provide theoretical reference.The results showed that there were significant effect on the Trifolium repens germination rate and germination speed under the heavy metal Cd and Pb stress.With the increase of concentration of heavy metal Cd and Pb，the inhibitory effect on the Trifolium repens seed germination rate and germination speed increased gradually.The Trifolium repens seedling length，root length，seedling dry weight dropped significantly.There were significant effect on the Trifolium repens seedling length，seedling root length and seedling dry weight under the heavy metal Cd and Pb stress.With the increase of concentration of heavy metal Cd and Pb，the inhibitory effect more obvious.
