某些树种种子由于深休眠、种皮厚、胚后熟等原因,发芽通常需要很长的时间。于是,人们极力寻找对种子生活力测定的方法,来快速测定种子发芽能力。这种测定方法的最大优点就是快速,不受种子的休眠、结构影响。现将常用的5种林木种子生活力的测定方法介绍如下:1四唑测定法1.1原理 Some tree seeds due to deep dormancy, thick seed coat, embryo ripening and other reasons, germination usually takes a long time. As a result, people are keen to find ways to determine the viability of seeds, to quickly determine the seed germination capacity. The biggest advantage of this determination method is rapid, not affected by seed dormancy, structure. Will now commonly used five kinds of tree seed vitality determination method described below: 1 tetrazolium assay 1.1 principle
