冬小麦是谷类作物中的主要作物,越冬时它的死亡导致籽粒严重欠收.因此,必须深入研究植株冬季的物质代谢.很多研究证明,游离氨基酸的含量不仅取决于品种本身所固有的内在因素,还取决于外界因素中最有调节作用的无机营养因素.但是游离氨基酸在提高冬小麦越冬性中的作用与栽培条件的关系问题(栽培条件更能说明冬小麦越冬性的生理生化机制),至今还研究得很不充分.本研究采用当地的品质好的冬小麦品种米隆诺夫808,按通用的方法设置田间试验,于1978-1980年在沃克涅什农学院试 Winter wheat is the main crop in cereal crops and its death leads to serious grain deficits during winter. Therefore, it is necessary to study the matter metabolism in winter in many plants.Many studies have shown that the content of free amino acids depends not only on the intrinsic factors intrinsic to the cultivars, But also depend on the most nutritious factors that have the most regulating effect on the outside world.But the relationship between the free amino acids and the cultivation conditions in the winter overwintering of winter wheat (cultivation conditions can better explain the physiological and biochemical mechanisms of winter wheat overwintering) Very inadequate.In this study, the local good quality winter wheat variety Milonov 808, according to a common method to set the field test, in the 1978-1980 Walker Nizhni agricultural college test
