| Popis: | To test the antagonistic ability of Bacillus amyloliquefaciens HY against lettuce sclerotinia rot caused by Sclerotinia sclerotiorum, an in vitro test, greenhouse test and growth chamber test were conducted. As a result of in vitro dual culture test for sclerotia of B. amyloliquefaciens HY, the mycelial growth inhibition rate was 70.7%. Mycelial tip was swollen, black, and had an irregular and deformed shape. In I-plate test, the antagonistic volatile compounds produced by B. amyloliquefaciens HY, the mycelial growth inhibition rate was 57.7% and the sclerotia germination inhibition rate was 46.7%. In addition, B. amyloliquefaciens HY had sideropore production capacity, phosphate solubillibty, and protease production capability, but B. amyloliquefaciens HY did not produce chitinase. In growth chamber test, the lettuce survival rate was 0% in the control group treated with only the pathogen, and 80% in the treatment group treated with of S. sclerotiorum and B. amyloliquefaciens HY by diluting 10 times of the lettuce survival rate. In addition, the lettuce survival rate of 80% was shown in the treatment group treated with the culture medium of B. amyloliquefaciens HY 50 times 1 week later after inoculation with S. sclerotiorum. |
