Protocorm development of Epidendrum fulgens (Orchidaceae) in response to different saline formulations and culture conditions

open access: yesActa Scientiarum: Biological Sciences, 2014
The asymbiotic technique of orchid seeds germination is an important method of mass production of seedlings. Studies on the best culture conditions for each species are important to obtain seedlings in less time and at lower costs.

Photosynthate transfer from an autotrophic orchid to conspecific heterotrophic protocorms through a common mycorrhizal network

open access: yesNew Phytologist, Volume 243, Issue 1, Page 398-406, July 2024.
Summary The minute ‘dust seeds’ of some terrestrial orchids preferentially germinate and develop as mycoheterotrophic protocorms near conspecific adult plants. Here we test the hypothesis that mycorrhizal mycelial connections provide a direct pathway for transfer of recent photosynthate from conspecific green orchids to achlorophyllous protocorms ...

Large-Scale In Vitro Multiplication and Phytochemical Analysis of Himantoglossum affine (Boiss.) Schltr.: An Endangered Euro-Mediterranean Terrestrial Orchid

open access: yesDiversity, 2022
Himantoglossum affine is a threatened terrestrial orchid. We aimed to optimize asymbiotic seed germination and direct embryogenesis and to analyze the phytochemical profile and physico-biochemical analysis of leaf and tuber. The individual use of organic

Asymbiotic seed germination and in vitro propagation of Cattleya trianae Linden & Reichb.f. (Orchidaceae)

open access: yesActa Agronómica, 2017
Cattleya trianae (Linden & Reichb.f., 1860), Colombian national flower, is in danger of extinction due to the destruction of its natural habitats and excessive collection for horticultural purposes. Therefore, in vitro culture is a tool for the conservation of threatened species.

1099. Neottia ovata (L.) Hartm.

open access: yesCurtis's Botanical Magazine, Volume 41, Issue 2, Page 199-206, June 2024.
Summary Neottia ovata (twayblade) is illustrated here (t. 1099). It is a widespread, temperate Eurasian species. A detailed description is provided, with notes on cytology and habitat. Given its wide distribution and the diverse range of habitats where it occurs, its conservation status is Least Concern in Europe.

Isolation and identification of orchid mycorrhizal fungi and \kur{in vitro} symbiotic/asymbiotic germination of terrestrial orchid seeds [PDF]

open access: yes, 2011
This thesis is a review on isolation, cultivation and identification of orchid mycorrhizal fungi and symbiotic and asymbiotic germination of terrestrial orchid seeds. Mycorrhizal fungi can be used in in vitro symbiotic germination. In vitro symbiotic and

Germination of Neotinea maculata (Orchidaceae) in nutrient media and water agar [PDF]

open access: yes, 2021
The asymbiotic seed germination of orchids is a complex process with considerable technical difficulties, due to the natural requirement of a plant-fungus symbiotic relationship under field conditions.
