摘要
利用已报道的 8种不同的甘薯茎尖培养基 ,对 6个甘薯栽培品种的茎尖分生组织进行培养。结果表明 ,不同甘薯品种茎尖培养成苗率差异较大。 6 BA 1 .0mg/L +NAA 0 .2 4mg/L+MS为相对广谱的培养基。 6个品种培养的平均成苗率达 65 .4%。金山 1 2 5 5、金山 5 7、湘75 5 5较易培养 ,其平均成苗率达 68.2 %。而新种花、夏引一号平均成苗率较低 。
Eight different mediums were employed to culture stem apex of 6 varieties in sweetpotato, the results showed that rates of regeneration of varieties are different. 6 BA 1.0 mg/L+NAA 0.24 mg/L+MS is more suitable to varieties used in the experiment than other mediums. The averoge rates of regeneration is 65.4 percent, rates of Jinshan1255, Jinshan57, Xiang75 55 are more than 68 percent, but rates of regeneration of Xingzhonghua, XiayinNo.1 are lower than that of them. The results suggested that effects of culture mediums for stem apex on rates of regeneration vary with varieties.
