在选育无芥酸油菜新品种工作中,需要用半粒法技术分析待栽培的单粒种子的脂肪酸组成与含量.在这方面,我们对原有的常规分析方法作了改进,研究了半粒法测定技术和快速分析方法.采用(氵岛)津GC-RIA型气谱仪进行测定.1.微量分析采用微量分析技术测定种子各部分(a.种皮与胚乳遗迹,b.外子叶,c.内子叶,d.胚芽)的含油量、脂肪酸含量等. In breeding new varieties of erucic acid, we need to analyze the fatty acid composition and content of the single seeds to be cultivated by using the semi-particle method.In this respect, we improved the original routine analysis methods and studied the half Particle size determination and rapid analysis were performed using a GC-RIA gas chromatograph (氵))) .1. Microanalysis Microanalysis was used to determine each part of the seed (a. Seed coat and endosperm relics, b. Outer cotyledons , c. inner cotyledon, d. germ) oil content, fatty acid content and so on.
