引言已经查明,种子去氢酶的活性强弱,或者说是去氢作用过程的快慢、与种子本身的生活力强弱呈正相关。根据种子染色部位及程度来检验种子生活力的“TTC定位图形法”,目前已被广泛应用,并列入国际种子检验规程。此法反应灵敏、快速。不仅能作为生活力的快速测定.而且还可用于活力测定。由于活力是比发芽率更能说明种子质量的一项指标,单靠TTC定位图形法,难以反映出活力的微小
INTRODUCTION It has been determined that the activity of seed dehydrogenase, or the speed of dehydrogenation, is positively correlated with the viability of the seed itself. According to the location and degree of seed staining to test the viability of seed “TTC mapping method” has been widely used and included in international seed testing procedures. This method is sensitive and fast. Not only as a rapid determination of viability, but also for the determination of vitality. Because vitality is more indicative of seed quality than germination rate, it is difficult to reflect the vitality
