| 摘 要： | 以柑橘褐斑病高抗品种Lw8,中抗品种L2,高感品种Lw14为实验材料,通过孢子喷雾法使柑橘褐斑病菌感染柑橘叶片,研究接菌0d、1d、2d、3d、6d、8d、10d时,柑橘叶片中超氧化物歧化酶(SOD)、过氧化物酶(POD)、过氧化氢酶(CAT)、苯丙氨酸解氨酶(PAL)、多酚氧化酶(PPO)、几丁质酶(CHT)酶和β-1,3葡聚糖酶(GLU)含量及活性变化规律与品种抗病性的关系。结果表明,接种前,两个抗病品种Lw8、L2中的POD、SOD、PAL、PPO 、GLU、CHT活性显著高于高感品种Lw14,CAT活性则与高感品种Lw14相近；接种后,3个不同抗性品种中SOD、POD、CAT、PAL、PPO 、GLU、CHT 7种防御酶活性较对照明显提高,但不同品种增加幅度不一致,除CAT外,其余6种防御酶活性均表现为抗病品种Lw8、L2增幅显著高于高感品种Lw14,且两个抗病品种一般在接菌3d内6种防御酶活性迅速升高并达到峰值；而高感品种Lw14防御酶(除CAT外)活性或增幅较小或较两个抗病品种滞后。本研究初步探讨了不同抗性品种接种褐斑病菌后7种防御酶的活性动态变化与柑橘品种抗病性关系,为进一步研究其抗病机理奠定基础。
