Abstract

In the current study, strain D1 was screened from saline-alkali soil of grassland by the method of plate confrontation. The inhibition rates against Fusarium equiseti BS1 , Fusarium oxysporum BF28 , Fusarium oxysporum BF19 and Fusarium solami BF36-2 were 70.81% , 76.00% , 67.80% and 65.70% respectively. Strain D1 was identified as Streptomyces ciscaucasicus by observation of colony morphology, physiological and biochemical characteristics and sequence analysis of 16S rRNA gene. The results of antimicrobial spectrum showed that the strain had antagonistic effect against 9 kinds of plant pathogenic fungi. The control effect of the strain on alfalfa root rot was 52.8% and it could promote rooting. The results showed that the strain D1 had potential as a biological agent
链霉菌对苜蓿根腐病的生物防治
本研究采用平板对抗法从草地盐碱土壤中筛选菌株D1。对木叶镰刀菌BS1、尖孢镰刀菌BF28、尖孢镰刀菌BF19和茄枯菌BF36-2的抑制率分别为70.81%、76.00%、67.80%和65.70%。通过菌落形态、生理生化特征及16S rRNA基因序列分析,鉴定菌株D1为顺高加索链霉菌。抗菌谱结果表明,该菌株对9种植物病原真菌均有拮抗作用。该菌株对紫花苜蓿根腐病的防治效果为52.8%,具有促进生根的作用。结果表明,菌株D1具有作为生物制剂的潜力
