新农抗702对水稻抗纹枯病诱导抗性的初步研究
A Study on the Mechanism of New Ag-antibiotic 702 to the Induced Resistance of Rhizoctonia solani
摘要
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 ·昺in),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.关键词
