On breeding Dendrobium candidum Wall.ex Lindl

On an appropriate medium,Fujian's Dendrobium candidum Wall.ex Lindl was studied for its seed germination,plantlet strength,rooting and transplantation.The results indicated that the seeds germinated well and quickly on the medium consisting of MS +sucrose 30 gL-1 +agar 7 gL-1.To strengthen the plantlet and encourage root formation,the best formulation was found to be 1/4MS +sucrose 40gL-1 +potato extract 100 mgL-1+agar 7gL-1.The transplanting survival rate,average number of new buds and average number of new buds that were longer than 3 cm could best be obtained when the mixture of sawdust and peat in the ratio of 1:2 was used for the plantlet transplantation.
