Many terrestrial orchids are currently at great risk for extinction as a result of a multiplicity of threatening processes. We focus on orchid seed germination capabilities in vitro, specifically germination capability of a threatened species, Anacamptis palustris, compared to three other more common species (A. laxiflora, A. morio, and A. papilionacea), and also discuss its potential impact on orchid distribution and conservation. Asymbiotic germination tests were performed with mature seeds using BM-1 medium. In vitro seed germination and protocorm developmental stages were evaluated up to 20 weeks after sowing. Significant differences in seedling development were detected among the species, and a correlation was evident between the rarity of the species and their germinability."

Germinazione asimbiotica in vitro di semi immaturi di Orchis palustris Jacq. / Sara Magrini in Studi Trentini di scienze naturali, vol. 90 (Année 2012)

Public [article]  inStudi Trentini di scienze naturali > vol. 90 (Année 2012) Titre : Germinazione asimbiotica in vitro di semi immaturi di Orchis palustris Jacq. Auteurs : Sara Magrini, Auteur ; Federica Bronzo, Auteur ; Silvano Onofri, Auteur ; Anna Scoppola, Auteur Année de publication : 2012 Langues : Italien (ita) Catégories : [Espèces (in biblio)] Orchis palustris [Thèmes] Germination des graines [Thèmes] Reproduction Mots-clés : reproduction in vitro 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."
