美国农业部最近取得了一项新的研究成果,即用简单、廉价的方法提纯高蛋白含量小麦种。宝泉岭秒研所育种室研究人员以六十一组种子作为观察对象,对用这种选法筛选出的高蛋白种子生长出的小麦,与普通小麦进行比较,12项实例表明:收获后,含蛋白质较多的种子长成的小麦,其蛋白质含量也较高,平均比普通小麦蛋白含量高15%,在个别最好的结果中,蛋白质含量甚至可增长19.6～20.7%。这种溶液浮选法是以蛋白质与淀粉比重不同的原理为基础的,小麦种子中的蛋白质吸收水分要 The United States Department of Agriculture has recently made a new study that uses simple, inexpensive methods to purify high protein content wheat varieties. Baochengling second Institute of breeding room researchers to 61 groups of seeds as the observation object, using this selection method of screening out of high-protein seeds grown in wheat, compared with ordinary wheat, 12 examples show: after harvest The protein content of wheat with more protein is also higher, averaging 15% higher than that of wheat. In some of the best results, the protein content can even increase by 19.6% to 20.7%. This solution flotation method is based on the principle of different protein and starch based on the principle, the protein in wheat seeds to absorb water to
