对我省三个主要栽培玉米杂交种及其亲本种子萌发期不同形态学部位的过氧化物酶酶谱的研究表明,不同杂种及其亲本的主酶带条数差异很大;同一杂种及其亲本的不同形态学部位的酶带条数差异显著,其中胚部位的酶带清晰度高,重演性好,迁移率最稳定,可作为鉴定真假杂种的最佳部位。杂种均出现“特征带”,故“特征带”可作为鉴别真假杂种的理论依据。 The study of peroxidase zymogram of different morphological parts of the three major cultivated maize hybrids and their parents at germination stage in our province showed that the number of major enzyme bands varied greatly among different hybrids and their parents. The number of bands in different morphological parts of the parents was significantly different. Among them, the bands of embryos were characterized by high definition, good repeatability and the most stable mobility, which could be used as the best site for identification of true and false hybrids. Hybrids have “feature zone”, so “feature zone” can be used as a theoretical basis to identify true and false hybrids.
