Background Tolumnia genus (equitant Oncidium) is a group of small orchids with vivid flower color. Thousands of hybrids have been registered on Royal Horticulture Society and showed great potential for ornamental plant market. The aim of this study is to establish an efficient method for in vitro propagation. Results Leaf explants taken from in vitro-grown plants were used to induce direct somatic...
The influence of light regime, explant position and orientation on direct embryo formation from leaf explants of two Phalaenopsis, P. amabilis and P. Nebula, were investigated to optimize the protocol for regenerating of this orchid. When explants were cultured in light, direct embryogenesis was retarded in both species. Embryos showed whitish to pale green in color and larger size than those cultured...
