摘　　要：通过对水芹种子的萌发试验及对水芹种子进行多种处理试验,结果表明:水芹种子发芽率低,存在着休眠。但种皮障碍、胚的生理休眠不是水芹种子休眠的主要原因;发芽抑制物质可能是引起水芹种子深休眠的关键性因素。Treatments had been carried out for germination of water dropwort, The results indicated that water dropwort seeds have a low germination percentage and dormancy characteristic. The main causes for dormancy of water dropwort aren＇t seed coat obstacle and physiological dormancy of embryo, but some inhibitors which may be the key factor cousing deep dormancy of water dropwort.
