| Abstract: | An experiment of rapid tissue-culture propagation on Dendrobium candidum seeds were conducted, that capsule have been gained through artificial pollination. The results showed that the seed setting rate of artificial hybrid breeding was 83%. The test results from induction of seed germination, rapid propagation of protocorm and rooting culture for strong sprouts showed that the best medium of seeding germination, protocorm rapid propagation and strong sprout rooting culture were I/2MS ＋ peptone 2g/L, 1/2MS ＋6 - BA 1.0 mg/L ＋ NAA O. 5 mg/L ＋ 15% potato and 1/2MS ＋ NAA 0. 5 mg/L ＋ 15% banana respectively, with the germination rate of 95%, multiplication coefficient of 5.7 and seedling height of 7.2cm and root number of 5.6 piece, respectively, the transplantation survival rate were over 90%. |
