| 摘 要： | 通过在兰州百合种植地采集百合枯萎病株,在中国科学院寒区旱区环境与工程研究所和兰州大学微生物实验室,使用常规组织分离法从切花百合枯萎病株中分离纯化得到7株病原真菌,结合形态学和分子生物学方法对所分离菌株进行鉴定,确定5株为尖孢镰刀菌,1株为茄类镰刀菌,1株为三线镰刀菌;将病原菌回接到百合组培幼苗中,发现尖孢镰刀菌、茄类镰刀菌和三线镰刀菌都对百合幼苗具有致病性,其中致病力最强的是尖孢镰刀菌,三线镰刀菌为首次发现的百合致病镰刀菌。以上分离确定了兰州百合枯萎病的病原菌,为百合枯萎病的防治提供了科学依据。

| Abstract: | Through study on lily bright in CAS lab , the research got seven pathogenic bacterias in Lanzhou lily , a-mong which 5 are fusarium oxysporum , 1 is eggplant oxysporum and 1 is three-wire oxysporum in the way of sepa-ration and purification .After getting back these pathogenic bacteria to the seedings , it has shown that these three oxysporums are pathogenicity to lily seeds and fusarium oxysporum has the greatest virulence while three -wire ox-ysporum is the first detected bacteria .The results above make scientific basis to lily blight prevention . |
