Symbiotic propagation of seedlings of Cyrtopodium glutiniferum Raddi (Orchidaceae)
Acta Botânica Brasílica, 2013 In nature, orchid seeds obtain the nutrients necessary for germination by degrading intracellular fungal structures formed after colonization of the embryo by mycorrhizal fungi.

Cyrtopodium paludicolum germination with two Tulasnella isolates
Acta Botânica Brasílica, 2017 Symbiosis between orchid seeds and mycorrhizal fungi has been reported to be a determining factor in the success of germination and protocorm development in vitro.

ASYMBIOTIC GERMINATION OF CYPRIPEDIUM CALCEOLUS VAR. PARVIFLORUM (ORCHIDACEAE) IN VITRO. [PDF]
HortScience, 1992 Seeds from mature seed pods of Cypripedium calceolus var. parviflorum were germinated on 1/4 MSMO (Sigma) + 100ml/l coconut water + 1% sucrose +/- 8g/l agar (pH 6.0), and with or without prechilling at 5C for 8 weeks.

Seed storage and asymbiotic germination of Hadrolaelia grandis (Orchidaceae)
South African Journal of Botany, 2017 Abstract Hadrolaelia grandis is an endangered species of orchid that is experiencing population declines due to habitat destruction and collection for ornamental purposes. Seed storage, in vitro germination and development of seedlings for propagation were investigated.

Asymbiotic seed germination and in vitro propagation of Brasiliorchis picta
African Journal of Biotechnology, 2016 Seed storage method for in vitro germination and propagation from leaves of Brasiliorchis picta was developed. Seeds were harvested and stored at -20 and -80°C for 1, 3, 6, and 12 months and were germinated on Knudson C (KC), Murashige and Skoog (MS), half-strength MS (½ MS macro- and micro-nutrients), and woody plant medium (WPM).

Asymbiotic Germination of Mature Seeds and the Seed Development of Vanilla Planifolia
, 2021 Abstract Background: Vanilla planifolia is an important tropical orchid for production of natural vanilla flavor. Traditionally, V. planifolia is propagated by stem cuttings, which produces identical genotype that are sensitive to virulent pathogens. However, sexual propagation with seed germination of V.

Cryopreservation without vitrification suitable for large scale cryopreservation of orchid seeds
Botanical Studies, 2018 Background Orchids are under threat from human activities and climate change, with populations limited to small geographic hotspots. This makes them ideal candidates for ex situ conservation.

ASYMBIOTIC GERMINATION OF ORCHID SEEDS ON CARBOHYDRAES OF FUNGAL ORIGIN [PDF]
New Phytologist, 1973 SUMMARYAsymbiotic germination of two orchid species on sugars found in orchid mycorrhizal fungi was studied. Trehalose and glucose both provided a satisfactory carbon source for growth of non‐photosynthetic orchid protocorms while mannitol did not.

South African Journal of Botany, 2020 Abstract In vitro cultivation techniques are viable alternatives for the germination and production of orchid seedlings in a short period. From another perspective, when studying the optimal germination conditions, knowing about the seeds viability is essential.
