高赖氨酸玉米又称高营养玉米,这是因为其籽粒蛋白质中,赖氨酸的含量为3.7％—4.5％,色氨酸的含量为0.8％—0.9％,都比普通玉米高。普通玉米籽粒蛋白质含量平均为10.4％,虽然在谷物中不算太低。但其蛋白质中含有人畜难以消化和吸收的醇溶谷蛋白占50—60％,为水稻的6—10倍。小麦的1.5—2倍,赖氨酸和色氨酸含量分别为0.2％和0.05％。 1.隔离种植 高赖氨酸玉米是隐性单基因控制,其生理生化作用仅在籽粒胚乳部分体现,只有在纯合状态时,才能表现高赖氨酸遗传效应。如果
High lysine corn, also known as high-nutrient corn, because of its grain protein, lysine content of 3.7% -4.5%, tryptophan content of 0.8% -0.9%, higher than the average corn. The average maize grain protein content is 10.4% on average, though not too low in cereals. However, its protein contains indigestible and absorbed by humans and animals accounted for 50-60% of prolamin, 6-10 times for rice. Wheat 1.5-2 times, lysine and tryptophan content were 0.2% and 0.05%. Isolation of high-lysine corn is a recessive single-gene control, its physiological and biochemical effects only reflected in the grain endosperm, only in the homozygous state, can show high genetic effects of lysine. in case
