大麦叶绿素缺失突变体分析
收藏 引用
核农学通报 1984年 第1期 5-6页
作者: m.j.constantin 王彩莲
由于大麦是具有2n=2x=14染色体的二倍体自花授粉作物,其染色体较大而且形态容易区别,所以广泛地用于遗传研究。以大麦为材料,可在同一处理群体中根据细胞遗传学和遗传学观点同时测定化学和物理诱变剂的效应。变剂处理种子或植株后,出现... 详细信息

大麦染色体畸变的分析
收藏 引用
核农学通报 1984年 第1期 3-4+30页
作者: m.j.constantin 赵孔南
栽培大麦已广泛应用于物理和化学因子对染色体效应的研究。大麦有7对染色体(2n=14),其中2对染色体带有随体,其他5对染色体的臂长比例不同;其染色体相对较长(6—8μm),易于鉴定。大麦发芽种子的根尖和芽尖有几个有丝分裂中心,在22℃水中... 详细信息
