When cultured on the medium with different auxin , root segments could elongate and branch, and the addition of 1mg/l IBA into the medium was the most suitable for long-term root culture. Calli could be induced from root explants in the presence of 2, 4-D and when transferred onto E medium, they transformed further into embryonic calli which could develop into normal plants through the stages of globular-embryo, heart-shaped embryo, torpedo-shaped embryo, cotyledonary embryo.

培养基中添加生长激素（IAA，IBA，NAA）能够诱导无菌苗根切段的生长和分枝形成；而1mg／l IBA的存在，最适合于根的长期离体培养。2，4-D的存在能够诱导根外植体脱分化形成愈伤组织，愈伤组织转移至E型分化培养基能够转变成胚性愈伤组织，并进一步经球形胚、心形胚、鱼雷形胚、子叶形胚发育成正常植株。

METHODS: 8 curved artificial root canals were prepared with stainless steel K files by the step-back technique, the root canals were digitally photographed, the images were analysed by the software Image-Pro Plus, the shapes and positions of the root canals were measured and analysed. SPSS10.0 software package was used for statistical analysis, paired-samples t test was used to compare the difference of the means among sample groups.
