摘　　要：用聚丙烯酰胺凝胶电泳技术对毕节地区栽培荞麦(Fagopyrum Mill)23个收集系的过氧化物酶同工酶进行了研究。结果发现:过氧化物酶同工酶共12条酶带,其中甜荞(F.esculentum)有8条酶带,而苦荞(F.tataricum)有10条。酶谱分析和系统聚类表明:荞麦在种内存在一定的遗传差异,但这种差异明显小于种间差异。The peroxidase isozyme of 23 cultivated buckwheats in Bijie region was studied by means of polyacrylamide gel eletrophoresis（PAGE）.The result showed that there were a total of twelve bands of peroxidase isoenzyme.Among them,F.esculentum and F.tataricum respectively had a total of eight bands and ten bands among different cultivals.The zymographs analysis and system analysis result showed that there were some genetic difference intraspecify,but the difference was not significant compared with interspecific crossing.
