在用14MeV 中子活化分析测定稻谷和大米中粗蛋白质含量及植物植株中氮、磷、钾和硅含量工作的基础上,发展了一种测定水稻抽穗结实期间稻谷中粗蛋白质含量动态变化的新方法,可以用来研究水稻抽穗结实过程中各种自然条件对颖果内蛋白质含量的影响。一、原理水稻植株扬花抽穗4—5天后,水稻植株的高度基本不变,灌浆初期颖果伸长较快,在以后的生长过程中,除颖果的长度继续缓慢变化外,主要是宽度变大,谷粒逐渐饱满。这期
Based on the work of measuring the crude protein content in rice and rice and the content of nitrogen, phosphorus, potassium and silicon in plant by 14MeV neutron activation analysis, a new method for determining the dynamic change of crude protein content in rice during heading stage was developed Method, which can be used to study the effect of various natural conditions on the protein content of caryopsis during heading and seed setting. First, the principle 4-5 days after heading flowering rice, rice plant height remained unchanged, early filling ciliary elongation faster, in the future growth process, in addition to the length of caryopses continue to slowly change, the main change in width Large, grain gradually full.
