The results were as follows:1 The explants with two phyllomes(about 0.2-0.5mm in size )were found to be suitable for virus-free seedling culture , which were cultured on solid MS medium supplement with 6-BA,NAA and IAA ,The result indicated that the plantlet was over 30% after three months.
主要结果如下： 1。取带2个叶原基(长度约为0.2-0.5mm)的茎尖为外植体，在附加6-BA、IAA和NAA的MS培养基上进行3个月的培养，成苗率达30％以上。另外，在切取茎尖前对薯苗热疗(37℃)4周，在基本不影响成苗率的同时，可大幅度提高脱毒率。

Can improve the survival ratio of seeding. Culturing in hormone media can make meristem tip survive once time, and the result is better than two-time-cultivation.3、The meristem tip with two phyllomes(0.3-0.4mm in size)were found to suitable for virus-free seeding culture that were cut from aseptic seeding, which led to higher survival and virus-free ratio, up to 72.1%and 54.2%.
在培养基中添加椰汁、香蕉汁等有机添加物可以明显提高成苗率。3、采用二次剥离茎尖的方法，从无菌试管苗上切取带2个叶原基(大小0.3-0.4mm)茎尖分生组织培养，成苗率为72.1%，脱毒率为54.2%。
