若了解玉米种子发芽率,可用生物化学法快速测定。常用方法有 1.四唑盐类法 首先配制溶液,用蒸馏水或pH值6～7的应用水配制浓度为0.25％～0.5％的溶液,然后把玉米种子沿种胚切成两半,取其中一半浸入溶液中,2～4小时后,取出种子用清水冲洗数次,逐粒观察,凡是种胚全部或主要构造染成鲜红色的为有生活力种子,种胚染成淡红色、不染色或其主要构造不染色的为生活力弱或无生活力种子。 If you know the germination rate of corn seeds, available biochemical method for rapid determination. Commonly used methods are 1. tetrazolium salt method first preparation of the solution, the use of distilled water or pH 6 ~ 7 water to prepare a concentration of 0.25% to 0.5% solution, and then the seeds along the embryo cut in half, whichever Half immersed in the solution, 2 to 4 hours, remove the seeds rinsed several times with water, observed by the grain, all embryos all or the main structure of bright red dyed vibrant seeds, embryo dyed into pink, non-staining Or the main structure of non-staining for the vitality of weak or non-viable seeds.
