| Résumé : |
"The present study is a first approach to in vitro asymbiotic reproduction of Orchis palustris, an endangered species due to the fragmentation of its distribution area and the reduction and alteration of its suitable habitat. Within a project of the Tuscia Germplasm Bank (Viterbo, Italy) for the ex situ conservation of wild orchids, seeds were collected from a population near the thermal spring at Bagnaccio (Viterbo, Italy). We investigated the effects of the maturity level of the seeds on the percentages of germination and on the development of protocorms, culturing mature seeds and immature ones collected from green pods. The percentages of seed germination and the developmental stages of protocorms were evaluated up to 10 months after sow-ing. In the cultures of immature seeds was possible to observe all the developmental stages of orchid seed germination, with a maximum percentage of germination of 33%. On the contrary has not been obtained any germination in the cultures of mature seeds." (source : auteurs) |
