Orthophytum grossiorum is a typical bromeliad from Atlantic forestry threatened of extinction. The objectives of this research were to select O. grossiorum clones with ornamental values easy to propagate in vitro, and establish in vitro propagation protocols for these clones. The project was developed in three steps: germination and in vitro selection of seedlings responsive to BAP (6-benzylaminopurine), selection of clones with ornamental values, and establishment of protocol for in vitro propagation of the selected clones. In the first step only 18.33% of plantlets germinated in vitro were responsive to BAP. These plantlets were selected and replicated in vitro several times, each replicated plantlet constituting a clone. In the second step these clones...
