Abstract:
Taking lettuce as material,by hydroponic experiments,the effect of heavy metal elements Cu,Cr and Pb on seed germination and seedling growth were studied.The results showed that there was no significant difference (P>0.05) in germination index among treatments at the low concentration (≤50 mg/L) of Cu,Pb solution.The inhibitory effect of Cr solution was the most obvious,and with the increase of the concentration,the inhibition had risen sharply.The inhibitory effect of the three kinds of heavy metal solution on lettuce seedlings root were significantly greater than bud.The seedling root length and the shoot length were decreased,with the increase of salt concentration of heavy metals.And the toxicity of three kinds of heavy metal salts was KCr2O3>Pb(NO3)2>CuSO4.
