经过几十年的研究,种子活力测定作为常规检测项目在世界多数的国家中取得了重大进展。种子检验技术的快速发展,使种子工作者越来越感到活力对农业生产的重要性,也是保证田间出苗率和生产潜力的必要手段,例如高发芽率的种子批具有较高活力,但两者不存在正相关,说明了高活力种子批在田间的表现差异是比发芽率更敏感的指标。 After decades of research, seed vigor determination has made significant progress as a routine test in most countries in the world. The rapid development of seed testing technology makes seed workers more and more aware of the importance of vitality to agricultural production and is also necessary for ensuring the rate of emergence and production in the field. For example, seed batches with high germination rate have higher vigor, but both There is no positive correlation, indicating that the difference in performance between highly active seed lots in the field is more sensitive than the germination rate.
