BI Rui-ming (Biology Department of Heze Normal College,Heze 274015,China)  
The results from the test showed that the liquid culture could improve growth and was suitable for fast reproduction of sterile cuttings in the tissue culture of sweetpotato.The sterile cutting's height of the liquid culture for 20 days was 63.16 percent higher than that of the solid culture on the same condition.The effect of the liquid culture for 20 days on height of plant was significant by variance analysis.The height,number of leaves of each plant,area of each leaf of the sterile cutting cultured by liquid for 60 days was respectively 59.43,106.70,49.82 percent more than that of the solid culture on the same condition.And the effect of the liquid culture for 60 days on height of sterile cuttings,on number of leaves of each plant was significant by variance analysis.
