【摘要】 用醇溶蛋白提取剂提取了300个水稻品系的醇溶蛋白,紫外吸收法测定了水稻种子中醇溶蛋白的总含量。发现水稻醇溶蛋白的总含量存在着较大的多态性。大部分水稻品系醇溶蛋白总含量在2~6 mg/g这个范围,占所测水稻品系总数的72.0%;醇溶蛋白总含量在16 mg/g以上的水稻品系很少,占所测水稻品系总数的1.0%;醇溶蛋白含量最高的为来自台湾的编号为T-9598的品系,总含量达23.73mg/g;含量最低的是来自古巴(Cuba)的编号为C-5360的品系,总含量仅为0.35 mg/g。本研究有助于筛选醇溶蛋白含量高的水稻品系,也可为水稻醇溶蛋白多态性研究提供科学依据。更多还原

【Abstract】 The total contents of rice prolamine of 300 lines were determined with ultraviolet absorbing.The results show that there is obvious polymorphism in rice prolamine content among the lines studied.The contents of rice prolamine are largely among 2~6 mg/g,accounting for 72.0%.Lines of more than 16 mg/g in prolamine content are seldom,only accounting for 1.0%.The highest one is T-9598 from Taiwan;the lowest one is C-5360 from Cuba.The result of this research is helpful for screening rice lines with relatively high prolamine content and for polymorphism analysis.更多还原
