国外最近研究出测定谷类作物种子发芽率的新方法。这种方法是:先将待测种子用水浸软,然后用氯化四唑(CH_2N_4-HCl)处理,处理后,有生活力的种子的氢化酶与氯化四唑反应变成鲜红色,无生活力的种子仍为原来的颜色。利用这种新方法,可以将相当费时间的种子发芽率测定缩短24小时左右,不仅快速,而且相当准确。 Recently, new methods have been developed to determine the seed germination rate of cereal crops. In this method, the seed to be tested is first macerated with water and then treated with tetrazolium chloride (CH 2 N 4 -HCl). After treatment, the hydrogenase of viable seeds reacts with tetrazolium chloride to become bright red. The seeds of vigor are still the original colors. Using this new method, the time-consuming seed germination rate can be determined to be shortened by about 24 hours, which is not only rapid but also quite accurate.
