多年来,国内外许多学者针对种子发芽率快速测定问题进行了大量研究。但这些方法大都局限于大粒种子,目前还很少有关小粒种子、尤其是烟草种子发芽率快速测定方法的报道,本试验着手于种子生活力与种子发芽率的相关性,寻求烟草种子发芽率快速准确的测定方法. Over the years, many scholars at home and abroad have conducted a great deal of research on the rapid determination of seed germination rate. However, most of these methods are confined to large seeds. At present, there are few reports on the methods for determining the germination rate of small seeds, especially tobacco seeds. In this study, the correlation between seed viability and seed germination rate was investigated. Accurate determination method.
