工业大麻种子生活力与发芽率的相关性研究

摘要

Adopting the method of TTC and paper bed germination, the seed viability and germination rate of industrial hemp (Cannabis sativa ) of four cultivars were respectively determined, to study the correlation between these two indexes. The correlation between seed viability (x) and germination rate ( y) was y = a + bx, and the correlation coefficient R =0. 912 9, which was extremely significant correlation. Utilizing the correlation between these two indexes, the germination rate of seed could be calculated after the viability was rapidly measured.%本项研究采用TTC法和纸床发芽法分别测定工业大麻4个品种种子的生活力和发芽率,分析其相互之间的关系.结果表明,种子生活力(x)与发芽率(y)符合y=a+bx的直线关系,相关系数R=0.9129以上,为极显著正相关；利用这种关系,可根据快速测定种子的生活力计算出相应的发芽率,其理论值与实验测定值具有一致性.此研究结果为估算工业大麻种子发芽率提供了简便的方法.
