中文摘要：
用聚丙烯酰胺凝胶电泳技术对毕节地区栽培荞麦（甜荞和苦荞）24个收集系的酯酶同工酶进行了研究。结果发现：酯酶同工酶酶带共13条，其中甜荞有9条酶带，而苦荞有6条。酶带分析及聚类分析表明：供试荞麦的酯酶同工酶谱在种间和种内均存在一定的差异，但种内差异小于种间差异。
英文摘要：
The esterase isozyme of twenty-four collections of cultivated buckwheat（ F. esculentum and F. tataricure） of Bijie region were studied by means of polyacrylamide gel eletrophoresis. The results showed that there were a total of thirteen bands of esterase isozymes. Among them, F. esculentum and F. tataricum respectively had a total of nine bands and six bands among different collections. The results of the zymographs analysis and the clustering showed that the variations of esterase isozyme zymograms were very great among different buckwheat species but less within the same species.
