| 摘 要： | 对5份西瓜材料采用苗期浸根法进行枯萎病抗性鉴定,并对西瓜感染枯萎病菌后,POD、SOD、CAT保护酶活性变化进行研究。结果表明,黑公子、广西三号、广西409属于感病材料,1号野生、2号野生、4号野生属于轻抗材料,5号野生属于中抗材料,3号野生属于高抗材料,抗病材料和感病材料的POD、SOD、CAT保护酶活性变化表现出不同的动态。

| Abstract: | Resistance of five watermelon cultivars to Fusarium wilt was identified. The changes in content of peroxidase （POD）, superoxide dismutase （SOD） and catalase （CAT） caused by infection Fusarium oxysporum Schlecht were detected. The results showed that three strains were susceptible, three strains were identified of low resistance, one of medium resistance and one of high resistance, respectively. There were difference in dynamics activities changes of three protective enzymes between susceptible and resistant strains. |
