| Abstract: | The blight pathogen of mango tree was identified and the biological characteristics of the pathogen were studied.Based on the culture characteristics,morphological character and pathogenicity,the pathogen was identified as Botryodiplodia theobromae Pat..The optimal temperatures for the mycelium growth of B.theobromae were ranged from 28 to 32 ℃,and the fatal temperature was 60 ℃ for 10 min.The range of the optimal pH values for the mycelium growth was from 5 to 9.Dextrose was the best among the tested carbon sources,while D-xylose was not propitious for the mycelium growth.Peptone was the best nitrogen source for the mycelium growth,and continuous illumination was most favorable to the mycelium growth. |
