Abstract:
Taking cherry collar rot tree as material,the pathogen was isolated and purified,and its pathogenicity was tested and r-DNA-ITS sequence was analyzed.The effect of pH and temperature on growth of mycelium were also studied.The results showed that four strains were isolated but only one strain could cause cherry collar rot.The pathogen was Ceriporia lacerate based on r-DNA-ITS sequence analysis.The ideal pH for mycelium was 4.0~7.0,the optimum pH was 6.0.The optimum growth temperature for the mycelium was 32~34℃,the maximum growth temperature was 38℃ and the lethal temperature was 42℃.
