In vitro asymbiotic germination of immature seed and formation of protocorm by Cephalanthera falcata (Orchidaceae). [PDF]
Ann Bot, 2006 Many Orchidaceous species are threatened globally by development and over-collection from their natural habitats for horticultural purposes. Artificial propagation from seeds is difficult in most terrestrial orchids native to temperate regions. Seed production is another limiting factor in the artificial propagation for these species because of the ...

Comparative Transcriptomics Analysis of the Symbiotic Germination of D. officinale (Orchidaceae) With Emphasis on Plant Cell Wall Modification and Cell Wall-Degrading Enzymes [PDF]
Frontiers in Plant Science, 2022 Orchid seed germination in nature is an extremely complex physiological and ecological process involving seed development and mutualistic interactions with a restricted range of compatible mycorrhizal fungi.

Symbiotic vs. asymbiotic seed germination in epiphytic orchids [PDF]
, 2009 We compared seedling growth of the epiphytic orchid, Tolumnia variegata in agar media with and without inoculated mycorrhizal fungi. Symbiotic germination produced more-developed embryos than asymbiotic germination. Differences were highly significant, although some isolates of Rhizoctonia-like fungi were parasitic on seeds.

Seed exudates of Sesbania virgata (Cav.) Pers. stimulate the asymbiotic phase of the arbuscular mycorrhizal fungus Gigaspora albida Becker & Hall [PDF]
Hoehnea, 2019 Sesbania virgata is a legume used in the restoration of degraded areas and forms a symbiosis with arbuscular mycorrhizal fungi (AMF). Its seeds exude secondary metabolites that may influence the colonization by AMF.

Complexities and Innovations in Orchid Germination: A Review of Symbiotic and Asymbiotic Techniques
Journal of Plant Sciences (Science Publishing Group)<i>Orchidaceae</i> is the second-largest family among flowering plants; one of the most fascinating characteristics is the morphology of the seed. One of the most important complications is that orchid seeds are tiny and lack endosperm, meaning they almost entirely depend on outside sources for nutrients while germinating or

Optimization of in vitro asymbiotic seed germination protocol for Serapias vomeracea [PDF]
The EuroBiotech Journal, 2019 Serapias vomeracea is an economically important orchid species which is over-collected from nature, because of its glucomannan-rich tubers. Thus, optimization of in vitro culture methodology in this species is required to meet industrial needs and to ...

Asymbiotic seed germination and in vitro seedling development of Paphiopedilum spicerianum: An orchid with an extremely small population in China [PDF]
Global Ecology and Conservation, 2015 Paphiopedilum spicerianum is listed as one of the country’s Wild Plants with Extremely Small Populations (PSESP). Procedures were developed for asymbiotic seed germination and seedling development aimed at producing seedlings for reintroduction.
