本文根据30个有代表性的谷子品种在全国10个生态点的试验材料,研究谷子蛋白质、脂肪、淀粉含量的品种间及地区间差异,同时对三者之间的相互关系及其与主要生态因子的关系进行了探讨.结果表明:①生态环境对谷子蛋白质、脂肪和淀粉含量有很大的影响,蛋白质和脂肪随纬度和海拔的增高而增加,而淀粉则相反.对光照时间敏感的品种,蛋白质、脂肪含量高,淀粉含量低.②不管是来自北部高原北片的品种还是全国各地的品种种植在北部高原北片,其蛋白质、脂肪的平均含量均最高.③蛋白质、脂肪、淀粉三者之间存在着极显著的关系,高蛋白质,高脂肪有可能结合于同一基因型. Based on the test materials of 30 representative millet varieties at 10 ecological sites throughout the country, this paper studied the differences in the contents of protein, fat, and starch among varieties and regions in the valley, The results showed that: ①Ecological environment had a great effect on the content of protein, fat and starch in millet, and the protein and fat increased with the increase of latitude and altitude, while the starch was the opposite. , Protein, high fat content and low starch content.②The average content of protein and fat in the North Plateau was the highest among the varieties from the northern plateau of the North Plateau or the cultivars from all over the country.③ Protein, fat, starch three There is a very significant relationship between the high protein, high fat may be combined with the same genotype.
