Abstract

7S/11S seed globulin ratios were determined for seven currently available Amaranthus hybrid lines i.e., Amaranthus K266, K283, K343, K432, K433, K436 and MT-3. Of the seven Amaranthus lines investigated, four lines had 7S/11S globulin ratios ranging from 0.47 to 0.81, while three lines were found to contain exclusively the 11S globulin form. In general, 7S globulins contained lower levels of essential amino acids such as tryptophan, methionine, lysine, histidine, phenylalanine, valine and isoleucine than the 11S globulins.

摘要

测定了7个现有苋菜杂交种系（即苋菜K266、K283、K343、K432、K433、K436和MT-3）的7S/11S种子球蛋白比率。在所研究的7个苋菜品系中，4个品系的7S/11S球蛋白比率在0.47至0.81之间，而发现3个品系仅含有11S球蛋白形式。一般来说，7S球蛋白所含的必需氨基酸（如色氨酸、蛋氨酸、赖氨酸、组氨酸、苯丙氨酸、缬氨酸和异亮氨酸）水平低于11S球蛋白。
