摘　　要：测定了反枝苋水浸提液对玉米、小麦、番茄、黄瓜和大豆等5种作物种子萌发和生长的影响.结果表明:高浓度的反枝苋水浸提液对几种作物种子萌发和生长有比较明显的抑制作用,而低浓度下则对番茄、黄瓜和大豆的种子生长有一定的促进作用;反枝苋茎叶部分水浸提液的抑制作用要强于地下部分.The seed germinaus and growth of tive crops including Zea mays. Triticum aestivum. Solanum lycopersicum. Cucumis sativus and Glycine max Merr. were determined by water extract of Amaranthus retroflexus L. The main results were as follows： High concentration of water extract of Amaranthus retroflexus L. could restrain the seeds germination and developing,while low concentration of the water extract could accelerate developing seed of Solanurn lycopersicum .Cueumis sativus and Glycine max Merr. The restraining influence of water extract from amaranthus retroflexus Ls. of the organs above ground was stronger than that from the underground.
