The population of black orchid (Coelogyne pandurata) in their natural habitat increasingly rare because the shrinking of forest and the collector of orchids who hunt it for sale. In addition, the size of orchid seeds are very small and doesn't have an endosperm (food storage) causes orchids can't grow well in their habitat. Therefore, to support the availability of this orchid conducted several experiments on the effect of culture medium with the substitution of foliar fertilizer types Gandasil D, Growmore, and Hyponex to growth of the black orchid seedlings. The purpose of this research to determine the growth of black orchid seedlings in vitro on alternative media with the addition of Gandasil D, Growmore, and Hyponex fertilizer. This research method using a completely randomized design (CRD) with one factor, namely the provision of a negative control treatment without foliar fertilizer {M0 (-)}, positive control {M0 (+)} with media MS, Gandasil D (M1), Growmore (M2), and Hyponex (M3) on the black orchid seedlings growth media with 5 repetitions. The results showed that the addition of Gandasil D, Growmore, and Hyponex fertilizer can affect the growth of black orchid seedlings. The application of foliar fertilizer types Gandasil D provides the best results for growing roots of black orchid seedlings with 6,00 units. Growmore fertilizer provides the best results for the growth of leaves with 9,20 units. Keywords : growth of seedlings, black orchid, culture media, foliar fertilizer.
