小麦不同抗赤霉病品种幼苗和不同品种幼苗感染赤霉病菌(Gibberella zeae(Schw.)Potch).其过氧化物酶,酯酶同工酶的酶谱具有明显的差异,感品种(2个)比抗病品种(2个)和耐病品种(2个)的过氧化物酶,酯酶同工酶活■更高,且酶带数目、颜色深浅、宽窄程度上都有差弱。这种小麦幼苗同工酶的差异,可作为比较不同品种抗赤霉病的生化依据,并为抗病有种及引种提供参考。 Gibberella zeae (Schw.) Potch was infected with different wheat cultivars with different resistance to Fusarium head blight and with different varieties of seedlings. The enzyme patterns of peroxidase and esterase isozymes were significantly different, ) Were higher than peroxidase and esterase isozymes of resistant varieties (2) and disease-resistant varieties (2), and were weak in the number of bands, color depth and width. This difference in isozyme of wheat seedlings can be used as a biochemical basis for comparing different varieties of scab resistance, and provide a reference for species and introduction of disease resistance.
