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。
Esterase isozymes were analyzed using polyacrylamide gel electrophoresis on wild millet, green foxtail and Tibetan wild. The results showed that the differences of isozymes between different varieties (types) within the species mainly showed the differences of minor bands and the relative activities of the corresponding bands, but their trends of activity distribution were the same; According to the category of millet, which belongs to a special type of millet, it is correct to designate the Tibetan wild material as “Tibetan millet”. The genus Gladys can be divided into 3 types according to their isozyme patterns, of which the type is origin of millet The most probable ancestor, the distribution of this type in the Loess Plateau in China further proves that the Loess Plateau is the origin of the origin of millet.
