Abstract:
Taking Bacillus amyloliquefaciens CMN1308 as materials，with the method of confront culture，the antibiosis effect on Rhizopus stolonifer，Fusarium solani，Stachybotrys chartarum,Cryphonectria parasitica，Lasiodiplodia theobromae，Penicillium expansum and Aspergillus niger was studied.The results showed that CMN1308 had stronger antibiosis effect on the seven major pathogens of chestnut.Among this，CMN1308 had a best biocontrol to P.expansum,the inhibition zone diameter was 27.1 mm.The further study on the stability of antimicrobial components in CMN1308 showed，the growth of P.expansum hyphal was limited by the antimicrobial components isolated from CMN1308，which also had a good stability to hot temperature，alkali and UV，but sensitive to acid.The results suggested that antibiotic effect and inducible resistance were the major mechanism of CMN1308 on chestnut pathogenic.The finding of this study would help to optimize the practical use of CMN1308 in the biological control of chestnut or other fruit rot caused by pathogenic fungi.
