In vitro assymbiotic germination of wild orchid seeds
Journal Title: Biotecnología Vegetal - Year 2007, Vol 7, Issue 3
Abstract
Among Cuban orchid species they are gathered in different threaten categories. There are not reports on how to achieve their mass propagation and in a short term. For these reasons, the study was aimed to achieve in vitro germination of seeds of fifteen species of wild Cuban orchids. This is also a contribution to the rescue and conservation of wild Cuban orchids. Capsules of Bletia patula, Encyclia gravida, Encyclia oxypetala, Encyclia phoenicea, Epidendrum nocturnum, Epidendrum secundum, Epidendrum wrigthii, Eulophia alta, Oncydium luridum, Phaius tancarvillae, Physinga polygonatum, Polystachya concreta, Polystachya foliosa, Prosthechea fragans and Schomburgkia lyonsii were collected, washed and disinfected. Three culture media were used to assess germination of seeds in each species. Results showed, for the first time, the possibilities for in vitro asymbiotic germination of the listed species. Germination of nine species in a period between six and forty weeks was proved. Also the wide variability of responses in this process among the species was observed.
