Abstract: Effects of water extracts of soil collected from replant woodlands of C.lanceolata (first rotation, second rotation) and mixed plantation soil of C.lanceolata and Michelia on the growth of C.lanceolata seedlings were studied. The results indicated that some allelopatic substances existed in replant soil of C.lanceolata. Extracts of replant soil significantly inhibited the growth of C.lanceolata seedlings,and reduced chlorophyll contents, length, numbers and weight per cm of new branches(p<0.05). The residues of decomposed root might be one of the possible resources of allelopatic substances in replant soil. The mixed plantation of C.lanceolata and Michelia could reduce the toxicity of allelopatic substances on the growth of the C.lanceolata seedlings.
