小麦种子的高蛋白含量和低蛋白含量分群法是在不破坏子粒的情况下,将子粒按蛋白质含量高低进行分群。较为适于在小麦品质育种中,用混合法处理杂种后代时应用,方法简便易行。这种方法原理是:小麦种子在1～2℃条件下,在水中浸泡10～15天。种子吸水量与其所含的蛋白质数量成正比;即蛋白质含量高的种子吸水量多。种子吸水后,本身的体积和比重发生变化,改变后的种子比重(称相对比重)的大小与种子吸水量成反比,即吸水量多的
The high protein content and low protein content grouping method of wheat seeds is to classify the grains according to the protein content without destroying the grains. The method is more suitable for wheat quality breeding, mixed method used to deal with hybrid offspring when applied, the method is simple and easy. The principle of this method is: wheat seeds in 1 ~ 2 ℃ conditions, soaked in water for 10 to 15 days. The amount of water absorbed by a seed is proportional to the amount of protein it contains; Seed water absorption, the volume and proportion of their own changes, the proportion of seeds after the change (known as the relative weight) is inversely proportional to the amount of water absorption, that is, the amount of water absorption
