Abstract: The experiment results showed that five of eight isolates infected the stored Chinese cabbages at the temperature of 0℃,5℃ and 10℃ respectively.Among them,Alternaria brassicicola,Colletotrichum higginsianum and Botrytis cinerea could sporulate at 0℃-5℃, but A. brassicae and A.raphani could only sporulate at 10℃.Since the temperature in the cellars,both of the traditional and forced ventilation types, did not exceed 5℃, A.brassicase and A.raphani could infect the stored cabbages, but could not sporulate. So the severity of the Alternaria black spot disease of Chinese cabbages in cellars mainly depend on the amount of the fungi brought in from the field.The result also showed that C.higginsianum,A.brassicae and B. cinerea could sporulate below 0℃,so the amount of those fungi could increase in both tydes of cellars,and the quantity of their isolates brought in from fields and the seventy of the disease showed less correlation.In addition,the temperature control in the cellars played an important part in the inhibition of those fungi. The cellars of the forced ventilation type introduced in Beijing was considered to be better for controlling the diseases.
