The efficiency of cryopreservation of seeds of five rare and endangered species of temperate orchids belonging to Platanthera and Dactylorhiza genera followed by their asymbiotic culture in vitro, as well as of in vitro cultured D. fuchsii protocorms (specific stage of orchid embryo development after release from the seed coat) was investigated. Germination rates of seeds after their exposure to liquid nitrogen were species-depended and could be either higher or lower than in the unfrozen…

TLDR
The orchid seeds and pollen are the most suitable propagules for cryopreservation of orchids due to their minute size and less space requirement and among the tissues, seeds are theMost reliable.
In vitro conservation of Dendrobium germplasm
TLDR
This review highlights 16 years of literature related to the preservation of Dendrobium germplasm and comprises the most comprehensive assessment of thorough studies performed to date, which shows reliable and reproducible results.
Study of Dactylorhiza Seeds (D. baltica and D. maculata) from the Orchid Collection of the Cryobank at Timiryazev Institute of Plant Physiology, Russian Academy of Sciences
TLDR
It was shown that comprehensive study of seed specimens collected from different habitats at different times may be synchronized by applying a cryopreservation technique and in vitro method for plant material cultivation.
Cryobiotechnology of Korean Orchid Biodiversity: A Case Study Using Cymbidium kanran
TLDR
High regrowth (86–90%) of rhizome sections after cryopreservation was achieved following the combination of ABA-and-sucrose preculture with desiccation over silica-gel to water content below 34%.
A cryopreservation protocol for ex situ conservation of terrestrial orchids using asymbiotic primary and secondary (adventitious) protocorms
TLDR
The protocols developed here provide a useful template for advancing cryoconservation of other orchid taxa, particularly rare and threatened species.
Cryopreservation the seeds of a Taiwanese terrestrial orchid, Bletilla formosana (Hayata) Schltr. by vitrification
TLDR
This study improves, an efficient protocol was established that maintained seed viability and enhanced the germination rates of seeds, compared with previously described cryopreservation methods, and the germinated seeds showed normal morphology of both vegetative and reproductive organs.
Cryoprotectant solutions in star orchid seeds and bamboo orchid conservation in liquid nitrogen
An alternative for the conservation of orchid species threatened with extinction is the seeds preservation for long periods by cryopreservation. This work aimed to evaluate the influence of cryogenic
