摘　　要： 研究香蕉束顶病病原感染健康蕉苗对香蕉束顶病病原的抗病性．初步结果表明香蕉束顶病病原可通过香蕉交脉蚜、伤口接触、土壤三种途径感染健康蕉苗，经过多糖处理的蕉苗对香蕉束顶病具较高的抗性，其次是青霉素，而用中药：路边菊、田基黄、半边莲等处理的蕉苗抗病性较弱． Banana bunchy top disease is one of serious diseases to harm banana farms.The experiments are oriented in the study about the disease resistance of the pathogen infecting heath banana seedlings on banana top disease pathogen.The primary results show that banana hunchy top disease pathogen infects health banana seedling by three means;banana intersecting vein aphides,contacts with the banana woods and soil.The banana seedling processed by polysaccharide will have a stronger resistance on banana bunchy top disease than that processed by penicillin.And the banana seedlings,processed by Chinese medicine herb of Indian Kalimeris,herb of Japanese St,John' swort and herb of Chinese lobelia,show weaker disease resistance.
