Developing a toolbox of Tier I tests to assess pesticides toxicity on the asymbiotic and symbiotic phases of arbuscular mycorrhizal fungi

Ecotoxicology and Environmental Safety
Soil microorganisms are a key protection goal in the European Union (EU) pesticide regulatory framework. Arbuscular mycorrhizal fungi (AMF) were identified as good proxies for assessing pesticides toxicity on the soil microbiota.

Symbiotic vs. asymbiotic seed germination in epiphytic orchids

, 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.

In vitro conservation and multiplication of Cymbidium finlaysonianum Lindl. - A horticulturally important floriferous orchid species

Acta Biologica Slovenica
The study is envisioned to assist ex situ conservation of horticulturally important endangered epiphytic orchid species, Cymbidium finlaysonianum. The in vitro cultures were initiated through an asymbiotic seed germination technique, using undehisced ...

Asymbiotic seed germination and in vitro seedling development of Acianthera prolifera (Orchidaceae)

South African Journal of Botany, 2019
Abstract The effect of the culture medium and of the addition of sucrose and activated charcoal on in vitro germination and protocorms development of Acianthera prolifera was analysed in order to establish a protocol for the seedlings propagation and ensure their conservation.

Reproductive Phenology and Asymbiotic Germination for Conservation of Endangered Miniature Orchid Specklinia digitale

Horticulturae
Specklinia digitale is an epiphytic orchid endemic to Mexico. The destruction of its habitat has resulted in it being regarded as an endangered species, and, to our knowledge, no effort has been made to establish ex situ conservation programs.
