摘要
探讨诱抗剂苯并噻二唑[Benzo-(1,2,3)-thiadiazole-7-carbothioic acid S-methylester,BTH]处理芒果叶片后,对4种抗病防御酶活性变化的影响。用200 mg/L的BTH水溶液对芒果叶片喷雾处理后,分别在0、24、48、72和96 h采取叶片,用于酶活性的测定,以清水喷雾的叶片为对照。结果表明,BTH诱导不同程度地提高了芒果叶片苯丙氨酸解氨酶(Phenylalanine ammonia lyase,PAL)、多酚氧化酶(Polyphenol Oxidase,PPO)、超氧化物歧化酶(Superoxide dismutase,SOD)和过氧化氢酶(Catalase,CAT)等酶活性。
In this study, we discussed the effect on mango leaves processed by BTH toward the change of activities of five defense--related enzymes. Processed by the spray of BTH solution with the concentration of 200 mg/L, the leaves were then collected after 0 h, 24 h, 48 h, 72 h and 96 h, of which the enzymatic activities were then determined by using water as the negative control. The results suggested that, the processing on mango leaves by BTH promoted the enzymatic activities of PAL, PPO, SOD and CAT respectively.
