The Biological Characteristics of Fusarium solani

There was no report about strawberry red stele root rot,which was caused of Fusarium solani in China.The biological characteristics of Fusarium solani was studied in this strawberry.The results showed as follows: the mycelial can grow better on the six kinds of N sources media and the nine kinds of C sources media,but worse on the potato L-arginine agar culture than others.The temperature range for mycelial growth was 10~35℃,25℃ was the optimum.The mycelial may grow from pH 3 to 12,pH 7 was the best.The effect of light on the mycelial growth was not evident.Pathogens were easy to produce conidia on various kinds of culture media.The conidia can germinate in six kinds of nutrition.The range of temperature for conidia germination was 10~35℃,27℃ was the optimum.The conidia can germinate within the treatments from pH 2 to 12.pH 6 was optimum,which the conidia lethal temperature was 62℃ for ten min.
