Germinación simbiótica y asimbiótica en semillas de orquídeas epifitas Symbiotic vs. asymbiotic seed germination in epiphytic orchids [PDF]

Acta Agronómica, 2009
Se compara el crecimiento de plántulas de la orquídeas epifita Tolumnia variegata en medios de agar con y sin hongos micorrízicos. Los métodos de germinación simbiótica produjeron embriones de T. variegata más desarrollados que los métodos de germinación

Royal jelly as a novel bio-stimulant for asymbiotic seed germination andprotocorm development in Phalaenopsis [PDF]

Journal of Horticultural Sciences
Orchid micropropagation is often limited by slow seed germination and early seedling development. This study evaluated the potential of royal jelly (RJ), a nutrient-rich organic substance, as a growth-promoting additive in the asymbiotic culture of five

In Vitro Propagation of Endangered Vanda coerulea Griff. ex Lindl.: Asymbiotic Seed Germination, Genetic Homogeneity Assessment, and Micro-Morpho-Anatomical Analysis for Effective Conservation [PDF]

Agronomy
In nature, orchid seed germination is extremely low, making in vitro asymbiotic seed germination essential for the propagation and conservation of endangered Vanda coerulea.

In vitro asymbiotic germination, seedling formation and tuberization of Orchis sancta

Turkish Journal of Biodiversity, 2022
Plant tissue culture techniques have recently become attractive tools for propagating rare and endangered species and producing their economically important natural products. Here, we introduce a protocol for an effective, fast and reliable production route of plantlets and tubers from salep orchid, Orchis sancta, a native orchid species growing wild ...

The influence of pre-treatment on germination of three species of Catasetum (Orchidaceae)

Journal of Seed Science, 2023
: Asymbiotic germination techniques are successful in species of the Catasetum genus. The diverse composition of the culture media can be critical; however, viable seeds are required for asymbiotic germination.

Plant and fungal gene expression coupled with stable isotope labeling provide novel information on sulfur uptake and metabolism in orchid mycorrhizal protocorms

The Plant Journal, Volume 116, Issue 2, Page 416-431, October 2023., 2023
SUMMARY Orchid mycorrhiza (OM) represents an unusual symbiosis between plants and fungi because in all orchid species carbon is provided to the host plant by the mycorrhizal fungus at least during the early stages of orchid development, named a protocorm.

Symbiotic status alters fungal eco‐evolutionary offspring trajectories

Ecology Letters, Volume 26, Issue 9, Page 1523-1534, September 2023., 2023
Evolutionary transitions in symbiotic status alter the evolution and ecology of fungal spore size. First, transitions in symbiotic status correlate with shifts in spore size during fungal evolution while symbiotic status explains more variation in spore size than climate variables among extant taxa.
