Abstract:
Glomerella cingulata is a new record species which was recently isolated anthrax pathogen from Dendrobium officinale,and was used as a test material.The biological characteristics of Glomerella cingulata were studied by the method of tissue culture,in order to find efficient and rapid prevention and control methods.To solve the problem of frequent occurrence of anthrax of Dendrobium officinale and its increasing trend.The results showed that the adaptability of Glomerella cingulata was strong and could grow on different medium.PDA was suitable for mycelial growth.It could grow at 10-35 ℃,and it was suitable for the growth of mycelium at 25-30 ℃.When the temperature was 28 ℃,the dense mycelia grew the fastest and produced the highest perithecia.The growth was better under different light conditions.But the light could promote the perithecia.It could grow under pH 5-12,but mycelium growth rate was the fastest when the pH was 8.The yield of perithecia was the highest when the pH was 9.It could be grown on different carbon and nitrogen sources.Sorbitol was the best for mycelia growth.The mycelia was dense in the maltose carbon source media and perithecia production reached the highest.Mycelia had the highest efficiency using to peptone.The water bath lethal temperature of mycelium was 50 ℃.
