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.

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.

Optimization of in vitro asymbiotic seed germination protocol for Serapias vomeracea [PDF]

The EuroBiotech Journal, 2019
Abstract 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 ...

Stimulation of Hyphal Ramification and Sporulation in Funneliformis mosseae by Root Extracts Is Host Phosphorous Status-Dependent

Journal of Fungi, 2022
A simulation of the environment inhabited by arbuscular mycorrhizal (AM) fungi could provide clues as to how to cultivate these obligate biotrophs axenically.

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).

Seed exudates of Sesbania virgata (Cav.) Pers. stimulate the asymbiotic phase of the arbuscular mycorrhizal fungus Gigaspora albida Becker & Hall

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.

Asymbiotic germination of Chloraea disoides Lindl. (Orchidaceae), a critically endangered orchid endemic to Chile

Gayana: Botanica, 2022
Degradation of ecosystems is one of the main causes of the global decline in biodiversity. Many species are threatened with extinction and urgent actions are needed. Chloraea disoides is a critically endangered terrestrial orchid endemic to Chile.

Effect of the medium composition on the asymbiotic germination and in vitro development of the Laeliocattleya hybrid

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.

Lipidomics of orchid seeds: from development to storage

Plant Biology, EarlyView.
The study tracked lipid changes from pollination to storage in two orchid species. Although both were desiccation‐tolerant and storable, differences in saturated and unsaturated fatty acid proportions during development led to different moisture contents and germination capacities.
