Abstract
为筛选鉴定桉树对焦枯病（Cylindrocladium quinqueSeptatum Morgan）抗性的生化指标，对福建省11个桉树主栽种系接种焦枯病菌前后关键防御酶系中的过氧化物酶(POD)和超氧岐化酶(SOD)活性及其同工酶变化进行了研究。结果表明：无论是桉树健叶还是接种后的病叶，体内POD、SOD活性均表现为抗病种系＞中抗种系＞中感种系＞感病种系，呈规律性变化；接种前后POD同工酶谱带数与桉树对焦枯病的抗性间不呈规律性变化，而SOD谱带数与抗病性成正比。从抗病育种角度出发可将接种前后桉树POD、SOD活性和接种后SOD同工酶谱带作为桉树对焦枯病抗性早期鉴定的生化指标。
