Biological characteristics of pathogen causing strawberry red stele root rot
The effects of different culture media, pH value, temperature, light, carbon and nitrogen sources on hyphal growth of pathogen causing strawberry red stele root rot were determined. The results show that the disease is caused by Phytophthora fragriae. Its biological characteristics are as follows;the optimum medium for the growth of pathogen is Czapek,the optimum temperature is 22℃,the optimum pH value is 6. Light has no effect on the pathogen growth. The optimum carbon source is sucrose,the optimum nitrogen is peptone and the worst is NH4Cl.
