用聚丙烯酰胺等电聚焦系统测定了２６ 个荷花品种过氧化物酶同工酶，共出现酶带有１６条， 等电点在ｐＨ４０～６０ 之间， 荷花品种的特征谱带有４ 条， 即ｐＨ 为４３２， ４７８， ４８８， ５０４。根据荷花品种中各酶带出现的频率 （Ｆ）， 计算各品种谱带的相同值 （ＳＩ）， 进行分析。
The polyacrylamide isoelectric focusing system was used to determine the peroxidase isozymes of 26 lotus cultivars. There were altogether 16 enzyme bands with isoelectric point between pH4.0 and 6.0, and the characteristic bands of lotus varieties There are 4, that is pH 4 32, 4 78, 4 88, 5 04. According to the frequency (F) of each enzyme band in lotus varieties, the same value (SI) of each band was calculated and analyzed.
