Biological characteristics and host range of the pathogen causing Brown Rot of Chinese Dwarf Cherry
[Objective]Biological characteristics and host range of pathogen causing Chinese dwarf cherry brown rot (Moniliniafructicola) were determined in the study.[Method]Biological characteristics were tested by measuring mycelial growth and spore germination under different conditions.Host range were determined by stab inoculation method.[Result]The temperature for mycelial growth ranged from 7 to 27 ℃,the optimum temperature was 22 ℃ and the optimum pH was 7.0 to 9.0.The speed of growth was faster under alternation of light and darkness every 12 hours.M.fructicola could make use of many carbohydrates and nitrogen sources,the optimum carbon sources were galactose,glucose and sucrose,and the optimum nitrogen source was peptone.The optimum temperature for conidial germination was 17 to 27 ℃ and optimum pH was 6.0 to 8.0.Illumination had no significant effect on conidial germination.The pathogen could infect pear,apple,nectarine,cherry,apricot,citrus and grape except kumquat and cherry tomato.The pathogen had the strongest virulence to cherry and nectarine and the weakest virulence to citrus.[Conclusion]The results could enhance the understanding of the disease and offer basis for the integrated control strategy.
