Investigation on effects for genotypes and region distribution to the grain amino acid contents of winter wheat
According to the measured results of 17 amino acid contents in the grain samples of 10 winter wheat genotypes in 7 experimental units of Henan Province,the difference of genotypes and the region distribution on the grain amino acid contents have been investigated,the results are shown as follow:there are not only heredity difference among genotypes but also among ecological environment conditions on the amino acid contents.The variation among environments is obviously bigger than that among genotypes on the amino acid contents,being 1.5 times as much as that among genotypes.The climate distribution and the change of soil types in experimental units are identical with the variation of amino acid contents.With improving of humid degree,the amino acid contents,the essential amino acid content and the non-essential amino acid content are gradually decreasing,but the per cent of the non-essential amino acid content in the amino acid content is increasing by degree.The chemical score of lysine content,which is related closely to the metabolism of human body,is lower than other amino acids and its variation is small.
