摘　　要：本试验以普通山药(Dioscored batatas Decne)的节间部为外植体,通过筛选附加在NA-AO+Zt10^(-5)M和NAA10^(-6)M+BA10^(-6)M的MS培养基上幼植株形成率高,并且可生产多个嫩茎,其根系发达,分化速度快,繁殖系数大。为了保持山药种的纯度和无病毒株的利用,可用此法进行大量的无性繁殖。The internode tissue of Chinese Yam(Dioscorea batatasdecne) were subjected to tissue culture. Ms dedium added by O M NAA +10^(-5) M ZT and MS dedium added bY 10^(-6) M NAA +10^(-8) M BA were found to be two Promising culture dediums for Chinese Yam asexual ProPogation in terms of Percentage of seedling formation, shoot differatation, and root growth. The exPeriment offers a potential way for large scale Production of high Purity virus-free yam seedlings
