分析了中国不同纬度地区1635份栽培大豆和1695份野生大豆种子的蛋白质含量,栽培大豆的平均含量为42.15±3.19%,变异系数为7.632%;而野生大豆分别为46.80±3.18%与6.795%。栽培大豆蛋白质含量总的趋势是与原产地纬度呈负相关,而最高量出现在30°—31°N地带。野生大豆则出现两个高峰区;30°—32N和43°N以北地带,讨论了中国大豆蛋白质含量高的特点及其开发利用,通过不同纬度野生大豆与栽培大豆蛋白质含量的比较,讨论了34°—35°N地带为栽培大豆起源地的可能性。 大豆是全世界最重要的豆科作物,种植面积占作物能第五位。大豆蛋白质是豆科作物中蛋白质含量最高,含有人体营养有重要价值含硫氨基酸最高的作物之一。大豆起源于中国,栽培历史约在五千年以上,曾为中华民族的健康成长做出了巨大贡献。国内外营养专家予言,在二十一世纪的人类食物构成中,大豆蛋白将占有远比今天重要的地位。目前,我国每人每日食用的蛋白质约为59.5克,比需要量75克低20%。为了满足我国人民生活、发展畜牧业的需要,充分利用我国丰富的大豆蛋白种质,选育高蛋白的品种,在“四化”建设中,具有战略意义。迫切需要弄清我国大豆蛋白资源的现状。关于我国大豆的蛋白质含量,过去只有全国代表品种分析资料,而缺乏大量分析资料。为此,我?
The protein content of 1635 cultivated soybean and 1695 wild soybean seeds in different latitudes in China was analyzed. The average content of cultivated soybean was 42.15 ± 3.19% and the variation coefficient was 7.632%, while that of wild soybean was 46.80 ± 3.18% and 6.795% respectively. The general trend of protein content in cultivated soybean is negatively correlated with the latitude of the origin of origin, while the highest amount appears in the region of 30 ° -31 ° N. Wild soybean appeared two peak areas; north of 30 ° -32N and 43 ° N, the characteristics of high protein content of soybean in China and its development and utilization were discussed. The protein content of wild soybean and cultivated soybean at different latitudes was discussed 34 ° -35 ° N zone for the possibility of cultivation of soybean origin. Soybeans are the most important leguminous crops in the world, accounting for the fifth largest crop area. Soy protein is one of the most protein-rich crops in leguminous crops and contains the highest value of sulfur-rich amino acids in human nutrition. Soy originated in China and its cultivation history is about 5,000 years or so. It has greatly contributed to the healthy growth of the Chinese nation. Nutrition experts at home and abroad said that in the composition of human food in the 21st century, soy protein will occupy far more important position than today. At present, our country’s daily consumption of protein is about 59.5 grams, 20 grams lower than the 75 grams required. In order to meet the needs of our people’s livelihood and the development of animal husbandry, it is of strategic importance to make full use of our abundant soybean protein germplasm and breed high-protein varieties in the construction of the “four modernizations.” There is an urgent need to find out the current situation of soybean protein resources in our country. With regard to the protein content of soybeans in our country, in the past only the national representative variety analysis data, but the lack of a lot of analysis of information. To this end, I?
