油分在种子中的积累是生物合成的典型范例,其最终产物的多样性和多功能性,使得可通过遗传控制来有目的地提高种子的品质。种子油分含量的自然遗传倾向于低油分方向筛选。而目前,一系列新的育种目标逐渐拓展,以适应生物油脂化工的发展。另外,生物技术的不断创新也为食用及非食用油料作物突变体驯化甚至创造全新作物提供了便利。本研究分析了突变体种子的油分和脂肪含量及脂肪酸的构成,其中第11、7、2、9和5号突变体油分含量较高,这些突变体脂类含量增加了两倍。气相色谱分析表明,第11号突变体脂肪酸含量最高,其次为第7、2、9和5号突变体,在14种脂肪酸中,顺式亚油酸含量在各突变体中均为最高。 The accumulation of oil in the seed is a typical example of biosynthesis, the versatility and versatility of its end product making it possible to purposefully increase the quality of the seed through genetic control. The natural inheritance of seed oil content tends to be screened for low oil content. At present, a series of new breeding objectives have been gradually expanded to meet the bio-oil chemical industry. In addition, the constant innovation in biotechnology has also facilitated the domestication of even mutants of edible and non-edible oil crops and even the creation of entirely new crops. In this study, we analyzed the oil content, fat content and fatty acid composition of the mutant seeds, in which the mutants 11,7,2,9 and 5 had higher oil content and the lipid content of these mutants tripled. Gas chromatographic analysis showed that the highest fatty acid content of No. 11 mutant was followed by the No. 7, No. 2, No. 2, No. 2, No. 9 and No. 5 mutants. Among the 14 fatty acids, the content of cis-linoleic acid was the highest in all the mutants.
