种子发芽率的高低,是种子品质好坏的一个主要标准,也是决定能否作种和决定播种量的重要依据。为了检验种子的发芽能力,我们通常的方法是做发芽试验。但这种办法一般需要7—10天,才能得到结果。如果采用测定种子生活力的方法,那末,就能在很短的时间内得到准确的结果。用“酸性复红染色法”测定种子生活力,方法简单易行。它是利用胚部死细胞能够被染色而活 Seed germination rate is the quality of the seed is a major criterion for good and bad, but also determine whether the decision to plant seeds and sowing an important basis. In order to test the germination capacity of the seeds, our usual method is to do the germination test. However, this method generally takes 7-10 days to get the result. With methods of measuring seed viability, accurate results can be obtained in a short period of time. Using “acid complex red staining method” to measure seed viability, the method is simple and easy to operate. It is the use of embryonic dead cells can be stained and live
