不同处理对野生亚麻种子萌发的影响

Effect of Different Treatment Methods on Germination of Wild Flax Seeds

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.
