摘要
以大白菜幼苗体内过氧化物酶（POD）活性的提高程度作为4种生物诱导剂E-2—2—1、E-1—1—7、E-5-1-1、E-11-1-1与3种化学诱导剂水杨酸（SA）、茉莉酸甲酯（MLS）、链霉素（LMS）筛选的标准，对大白菜软腐病寄主诱导剂进行筛选。表明，浓度为10^9cfu／mL的生物诱导剂E-2—2—1、E-1-1—7和2种化学诱导剂SA、LMS诱导处理大白菜幼苗后，POD活性有较大幅度的提高（P〈0．05），初步筛选这4种诱导因子作为提高大白菜抗软腐病能力的诱导剂。
Taking the activity of induced POD in seeding of Chinese cabbage as a standard, resistant inducers to soft rot disease were screened. The results indicated that activity of POD in hosts treated by biological inducers with concentration of 10^9cfu/ml and chemical inducers was obviously raised（P〈0.05）, thus the four inducers E-2-2-1, E-1-1-7, SA, LMS were primarily screened.
