以保加利亚尖椒为对照,在接种疫霉菌前后,对转RS-AFP2辣椒进行病情调查,并对叶片中的SOD、POD、PPO、PAL、SOD同工酶和POD同工酶进行分析,检测转RS-AFP2辣椒的抗病性效果。结果表明:①保加利亚尖椒在接种后SOD活性立即开始上升,第3天后开始下降,在第7天表现出疫霉病症状,转RS-AFP2辣椒在接种后24 h才开始上升,第7天开始下降,不表现发病病症;②接种前,转RS-AFP2辣椒POD活性明显高于保加利亚尖椒,接种后第5天保加利亚尖椒开始高于转RS-AFP2辣椒;③无论在接种前还是接种后,转RS-AFP2辣椒PPO和PAL酶活都明显高于保加利亚尖椒;④转RS-AFP2辣椒和保加利亚尖椒在接种前和接种后,SOD同工酶条带数都一样,...

Used Bulgaria pepper as control, the RS-AFP2 pepper was surveyed on disease infection, the SOD.POD.PPO. PAL.SOD isozyme.POD isozyme were analyzed before and after Phytophthora capsici infected, which was to test the disease-resistant effects of RS-AFP2 pepper. Results ： ①The SOD activity in Bulgaria pepper increased immediately after infected with Phytophthora capsici, but, it started to decline on the third day, when on the seventh day, the plants presented the symptom of the disease. However, the SOD activity in the RS-AFP2 pepper started t...
