| 摘 要： | 为研究新农抗702对水稻的抗性诱导机制,用新农抗702处理水稻叶片,叶片表现较明显的抗纹枯病作用；用不同质量浓度新农抗702在不同时间下诱导稻苗,测定稻苗体内防御酶的变化,结果表明:质量浓度为1.5 μg/mL,处理12 h时,过氧化物酶(POD),多酚氧化酶(PPO)、苯内氨酸解氨酶(PAL)、过氧化氢酶(CAT)的活性分别达到:16.58 U/(g· min)、160U/(g·s)、234.02 U/(g·min)、37.67 U/(g · min),酶活性较高,而新农抗702对超氧化物歧化酶(SOD)无显著的影响. |

| Abstract: | In order to study the mechanism of new Ag-antibiotic 702 to the induced resistance,rice leaves induced by new Ag-antibiotic 702,exhibited obvious resistance to Rhizoctonia solani.Then the rice leaves were treated with different concentrations of new Ag-antibiotic 702 and different time and then their defense enzyme activities were measured and analyzed.The results showed that when the concentration of new Ag-antibiotic 702 was 1.5μg/mL,treating-time was 12 h,the enzyme activities were the highest.The activities of peroxidase(POD),polyphenol oxidase(PPO),phenylalanine ammonia-lyase(PAL),catalase(CAT) were 16.58 U/(g·min),160 U/(g·s),234.02 U/(g·min) and 37.67 U/(g·min).However,the activities of SOD treated with new Ag-antibiotic 702 were not significant. |
