Fluridone stimulates in vitro seed germination of a rare hardy terrestrial orchid (Platanthera leucophaea) [PDF]

Botanical Studies
Background Seeds of temperate terrestrial (hardy) orchids are considered more difficult to germinate compared to their tropical epiphytic counterparts, presumably because they have higher levels of abscisic acid (ABA) in their seed coats which prevents ...

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

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.

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

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.

Asymbiotic seed germination and multiplication of an endangered orchid – Paphiopedilum venustum (Wall. ex Sims.) [PDF]

Acta Societatis Botanicorum Poloniae, 2016
The present study was intended to facilitate ex situ conservation of Paphiopedilum venustum, a highly floriferous endangered terrestrial orchid species. A protocol was established for in vitro propagation and shoot multiplication.

Asymbiotic in vitro seed germination, in vitro seedling development, and ex vitro acclimatization of Spiranthes. [PDF]

Appl Plant Sci, 2022
Abstract Premise Reproducible seed propagation and production protocols were developed for Spiranthes and related taxa to facilitate ex situ conservation practices. Methods and Results Spiranthes seeds were scarified for 3‐ and 10‐min intervals in 10% sodium hypochlorite solution, then cultured on three seed germination media.

Broad Fungal Compatibility and Seed Size May Facilitate Invasiveness in Two Asian Terrestrial Orchids Spathoglottis plicata and Arundina graminifolia [PDF]

Ecology and Evolution
Two Asian orchids, the bamboo orchid (Arundina graminifolia) and the Philippine ground orchid (Spathoglottis plicata), are expanding into South and Central America, the Pacific, and Africa. Here, we tested whether seed traits and low in vitro selectivity

Circannual Clock in Laelia speciosa (Orchidaceae) Through Dormancy vs. Germination Dynamics of Seeds Stored Under Controlled Conditions [PDF]

Plants
This study aimed to determine the dynamics of dormancy using triphenyl tetrazolium chloride (TTC) and asymbiotic germination in Laelia speciosa (Kunth) Schltr. seeds stored for three years and one year at different temperatures.

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.
