大麦、油菜的抗耐病性与过氧化物酶同工酶的关系

Relationship between Diease Resistance and Tolerance and the Peroxidase Isozymes of Barley and Rape

利用过氧化物酶同工酶分析比较了上海地区大麦抗、感黄花叶病的品种和油菜耐、感菌核病的品种间的酶谱差异 .结果表明 ,两类作物的抗耐病性在酶谱上呈现相同趋势 .感病品种的酶带数量和强度要高于抗耐病品种 .试验显示 ,过氧化物酶同工酶分析可作为大麦。

Zymogram of peroxidase isozymes of the resistance to barley yellow mosaic virus (BaYMV) in barly varieties and the tolerance to sclerolinose in rape varienties in Shanghai region were compared. The result shows that the disease resistance and tolerance of the two crops tend to the same tendency. The bands of the sensitive varieties are more than that of the varieties of disease resistance and tolerance. The experiment indicats that analysis of peroxidae isozyme may be a method for identifying in resistance breeding of barley and rape.
