Title: Studies on the Identification and Biological Characteristic of Chinese Prickly Ash
Abstract: The paper reports the identification of the causal organism of root rot of Chinese prickly ash and its biological characters.The results showed that the causal organism was Fusarium solani.The growth temperature range of mycelium was 5~40℃,and the optimum temperature range was 25~30℃.The pH range of mycelium was pH 3~10,and the optimum range was pH 5~7.Conidia could not germinate if the relative humidity was lower than 90%,the germination rate was the highest in the water drop.Illumination affected the germ growth and developments less.The lethal temperature was(60℃),10 minutes lasted,Sucrose and lactose is the best carbon nutrient,NaNO_3 and(NH_4)_2SO_4 is the best nitrogen nutrient.
