Abstract
The biological characteristics of Fusarium solani was studied in this paper.The results showed as follows: the mycelial could grow better on the most of culture media,but worse on the potato yeast agar culture than others.The temperature range for mycelial growth was 10~35℃,25℃ was the optimum.The mycelial might grow from pH3 to pH12,pH7 was the best.The effect of light on the mycelial growth was not evident and mycelial lethal temperature was 64℃,10min.Pathogens were apt to produce coidia on the inclined plane of the potato,the conidia were the mostly large-scale style,but the ones that produced on PSA inclined plane were mainly small-scale type,it was difficult to produce conidia on various kinds of culture media.The conidia could germinate in most kinds of nutrition.The range of temperature for conidia germination was 15~35℃,30℃ was the optimum.The conidia could germinate within the treatments from pH2 to pH12.pH7 was optimum,which the conidia lethal temperature was 58℃,10min.
