Abstract：Effects on seed germination,seedling growth and root morphology in cucumber were studied by treatments of Cd,Pb. The results showed that the seed germination indices,shoot and root fresh weight of cucumber decreased with increasing concentration of Cd、Pb.The total root length、total surface area of cucumber roots were decreased with increasing concentration of Cd,Pb also.the average diameter of cucumber roots were increased with increasing concentration of Cd,Pb under the low consistence, but were decreased obviously under the high consistence.The single effect of Cd on cucumber seed germination and roots was obvious than that of Pb．‘Yuyi201’ cucumber was more tolerant to Cd and Pb than ‘Jiangshulufeng’ cucumber.
