众所周知生活力(Vialility)是种子质量的一项指标。在实验室最适条件下,通常是以快速测定发芽力的指标来表示生活力的。但是人们从长期实践中发现,室内所测得的发芽率与田间出苗率之间往往存在较大的差距。由于单依靠发芽率不足以表明种子的优劣,于是在1960年后出现了种子活力(vigos)的概念, It is well-known that Vialility is an indicator of seed quality. Under laboratory conditions, vitality is usually expressed as an indicator of rapid germination. However, people find from long-term practice that there is often a big gap between the germination rate measured in the field and the emergence rate in the field. Since the reliance on the germination rate alone was not sufficient to show the merits of seeds, the notion of vigos emerged after 1960,
