在甘薯微茎尖组织培养中，材料消毒选择0．05％HgCl2溶液，时间9－10分钟，培养基琼脂浓度0．7％较为适宜。茎尖分化培养首选激素6－BA，浓度为0．25－2mg／L，或NAA0．01mg／L＋6－BA0．5mg／L＋GA30．1mg／L，成苗率可达85％左右。
In sweetpotato tissue culture, 0.05% HgCl2 solution was used for disinfection of materials, with a time of 9-10 minutes and a medium agar concentration of 0.7%. The optimal hormone 6-BA for shoot tip differentiation culture was 0.25-2mg / L or NAA 0.01mg / L + 6-BA 0.5mg / L + GA 30.1mg / L.
