Abstract We discussed the effects of different treatments on seed germination rate and germination vigor of waternut〔Eleocharis tuberosa（Roxb.）Roem. et. Schult.〕, including lamination at low temperature, peeling off episperm by friction, soaking seed in vitriol, in warm water, and in different concentrations of GA3 and 6-BA, by different ways of preservation, different temperatures and lights, using different cultivar seeds, etc. The result showed that the germination rate was the highest when lamination at 4 ℃ for 48 d, soaking in vitriol for 10 min+40℃ water for 50 min, with germination temperature at 25 ℃. The seed did not germinate at 30 ℃. Preservation in sand was better than in water. Germination in intermittent light was better than in dark. The cultivar of‘Shayang’waternut showed the best germination rate, germination vigor and germination index.
