Cypripedium flavum, known as the rare lady’s slipper orchid, is one of the endemics with a yellow flower in China. Due to its conservation and commercial requirement, establishment of an efficient method for micropropogation is urgently needed. Multiple shoots were obtained by placing seedlings from seeds of C. flavum on Harvais media supplemented with two cytokinins (BAP or KIN) used alone or in addition to different concentration of potato homogenate. The effect of BAP was better than that of KIN on shoot multiplication. The Havais media supplemented with BAP (2.22 μM) and potato homogenate (20 g l−1) was the most effective, providing high shoot multiplication frequencies (95%) associated with a high number of shoots per explant (2.55 shoots/plant). For root formation, high rooting and survival were achieved using 1/2 Harvais media supplemented with 0.6 g l−1activated charcoals. High-level activated charcoal increased the number and the length of roots because the activated charcoal could absorb BAP in the media. This study demonstrated that C. flavum could be micropropagated by using multiple shoots of seedlings derived from mature seeds.
