3.大麦:罗马尼亚谷物和经济作物研究所(1967)用热中子辐照大麦干种子,选到旦白质含量达15.1～17.0%大麦突变品种,比原品种旦白质含量提高1.8～3.0%;阿根廷植物技术研究所(1969)报道他们已查明大麦胚乳中旦白质含量、旦白质部分和氨基酸成分之比例、突变体与原品种在这方面均有明显差异。突变体 C_(64),比原品种子粒大且旦白质含量增高50%,从而打破了旦白质含量与子粒大小之间的负相关关系。这一事实也为苏联克拉斯诺达尔农科所(1973)在大麦诱变试验中所证明。而在旦白质成分上见到明显差异的突变体C_(61),其酒精溶解部分的含量降低50%,而剩余部分提高20%。此外,在高旦白质突变体与原品种旦白质成分比例不变情况下,前者的氨基酸含量比后者都有所提高。西德的苏列楚
3. Barley: The Romanian Institute of Cereal and Economic Crops (1967) irradiated dry seeds of barley with thermal neutrons and selected barley mutant varieties with a protein content of 15.1-17.0%, which increased 1.8-3.0% than the original varieties. Argentine Institute of Plant Technology (1969) reported that they have identified the barley endosperm in the protein content, the proportion of white matter and amino acid composition, mutants and the original species are significantly different in this regard. Mutant C_ (64), which is larger than original seeds and the content of white matter increased by 50%, broke the negative correlation between protein content and grain size. This fact is also evidenced by the Soviet Krasnodar Institute of Agricultural Research (1973) in barley mutagenesis experiments. Mutant C_ (61), which showed obvious difference in protein content, reduced the content of alcohol-soluble fraction by 50% and the remaining fraction by 20%. In addition, the amino acid content of the former is higher than that of the latter when the proportion of high protein white matter mutants and the original breeds is unchanged.
