| 摘 要： | 采用杯碟法研究了放线菌菌株的抑菌活性。研究发现,4期菌株SY-5无论是活体还是发酵液对6种供试病原菌均表现出强烈的抑菌效果,发酵滤液稀释10倍后对玉米弯孢病菌的抑制率达81.8%。

| Abstract: | A total of 156 strains of actinomycetes were obtained from 20 soil samples from Liaoning Province and Jilin Province.Six fungi such as Alternaria Solani,Gibberella fujikuroi,Curvularia lunata,Alternaria alternata,Fulvia fulva,Exserohilum turcicum were picked up as indicator in this test.14 strains showed inhibition rings of over 15 mm in diameter.The inhibition activity of fermentation broth was measured by the cup-dish method.4 strains with inhibition rings with over 15 mm in diameter were used for the further tests.It was found that both strain SY- 5 and its fermentation broth had strong inhibition effects on these 6 fungus.10 % of the fermentation broth had inhibition effect reached 81.8 %. |
