种子品质是决定农林生产成败的主要因子之一,特别是随着现代农业发展,单粒播种及一次收获成熟作物逐渐提到日程上,它要求人们能在播前准确迅速地对种子品质作出评价。对此,常规发芽试验已难以满足。因为发芽率通常总是指在最适条件下种子最充分发芽的程度,因此它只能在死活种子中间划线,对于那些中轻度变质的种子则无法表明它们之间的差异。也即中轻度变质的种子在发芽试验中虽
Seed quality is one of the major determinants of the success of agriculture and forestry. In particular, with the development of modern agriculture, single cropping and harvesting of ripening crops are gradually on the agenda, requiring that people evaluate their quality accurately and quickly before sowing . In this regard, the conventional germination test has been difficult to meet. Because the germination rate is usually always the degree at which the seed germinates most under the most appropriate conditions, it can only be crossed between the live and dead seeds, whereas for those with moderate deterioration, the difference between them can not be indicated. That is, mildly degenerate seeds are in germination test
