为探索打破野生亚麻种子休眠的最佳方法，采用5种方法对野生亚麻种子进行处理。结果表明，在40～50 ℃温汤中浸种10 min后，野生亚麻种子发芽率为76.67%～81.33%；流水冲洗24～48 h后，发芽率55.33%～58.67%。低温处理对野生亚麻种子发芽率影响不明显，机械损伤和硫酸处理致使种子失去发芽能力。

The five methods are used to treat hard seeds of Linum stelleroides Planch to explore the optimum method. The result shows that hot water dip under 40~50 ℃ after 10 minutes had the best effect with the germination rate is 76.67%~81.33%; the germination rate is 55.33~58.67% after pipelined processing 24~48 hours. It is not obvious on Linum stelleroides Planch seed germination rate of low temperature freezing， and the seeds germinate lost capacity of mechanical damage and dense sulfuric acid.
