| 摘 要： | 以2个抗病和2个感病的大白菜品种为材料,研究人工接种甘蓝链格孢后叶片过氧化物酶(POD)、过氧化氢酶(CAT)和苯丙氨酸解氨酶(PAL)活性的动态变化及其与抗病性的关系。结果表明:抗病品种在受到甘蓝链格孢侵染时,叶片内POD活性反应较感病品种快,但POD活性值上升比感病品种小;抗病品种在受到病原菌侵染时,叶片内CAT活性反应快,且一直维持在一个较高的水平,而感病品种在受病菌侵染后叶片内的CAT活性变化缓慢,变化程度低;另外无论是抗病品种还是感病品种的PAL酶活性在接种后的动态变化有相似规律,接种后所有品种的PAL酶活性均比未接种前增加。

| Abstract: | The relationship between the activity of CAT,POD,PAL and the resistances to Alternaria brassicicola were studied.The results showed that POD activity in the resistant cultivars raised earlier than in the susceptible ones after inoculation with A.brassicicala,but the highest point of POD activity in the resistant cultivars was lower than in the susceptible cultivars;The activities of CAT in the resistant cultivars raised earlier and kept a high level after inoculation with A.brassicicola,but slow and small c... |
