摘要
采用聚丙烯酰胺凝胶电泳技术 ,对谷子、青狗尾草和西藏野生材料进行酯酶同工酶分析。结果表明 :种内不同品种 (类型 )间的同工酶谱差异性主要表现为少数酶带的差异及相应酶带相对活性不同 ,但它们的活性分布趋势是相同的 ;西藏 1 90野生材料应划归于谷子的范畴 ,属谷子的一种特殊类型 ,将西藏野生材料定名为“西藏野谷子”是正确的 ;青狗尾草按照其同工酶谱可划分为 3种类型 ,其中类型 是谷子起源的最可能祖先 ,该类型在我国黄土高原的分布进一步证明黄土高原是谷子起源中心地。
Using polyacrylamide gel electrophoresis (PAGE),analytical results are reported in this paper on esterase zymograms in foxtail millet and related species. The results indicated that esterase zymogram patterns differentiation of intraspecific different varieties is due to differentiation of small number isozyme band and of activity of corresponding band, but the activity disperse of EST isozyme PAGE patterns in intraspecific varieties is unanimous. Tibet 190 wild material and foxtail millet are the same taxonomical group. It is a special type of foxtail millet. It is proper that Tibet 190 wild material was named Tibet wild millet. Green foxtail (S. viridis) is divided into 3 types according to esterase zymogram patterns, in which that the type Ⅱ may be the ancestor of cultivated millet in the most possibility. The type Ⅱ is distributed over the Loess Plateau, and this has further proved that foxtail millet is originated from the Loess Plateau.
