Conservation of black orchids (Coelogyne pandurata Lindl.) is a high priority because the natural population is decreasing significantly. A typical method for orchid conservation is farming. The aims of this research were to examine the effects of adding benzyladenine (BA) to medium on the total number of buds, shoot initiation, and the number and length of roots. Our research method was based on a completely randomized design, in which various concentrations of BA (0, 0.5, 1, 1.5 and 2 ppm)

The most prominent effect was seen at 0.5 and 1 ppm/L BA; however, increasing the concentration over 1 ppm/L inhibited bud growth and the number and length of roots. Our data suggest that optimization of the BA concentration added to medium leads to accelerated growth of black orchid plantlets. In vitro propagation with the addition of BA to Vacin and Went media can be applied for black orchid conservation.
