Orchids are distributed worldwide, and some species have considerable economic value. Orchid seeds are minute in size, simple in structure, and deficient in nutrient reserves. Asymbiotic seed germination is an important propagation strategy for orchids. MicroRNAs (miRNAs) play an essential role in seed germination.

Asymbiotic germination of Prasophyllum (Orchidaceae) requires low mineral concentration
Australian Journal of Botany, 2023Context Asymbiotic germination is used for propagation of orchids and to assess seed viability. However, asymbiotic germination media remain undeveloped for Prasophyllum (Orchidaceae), a genus with 39 threatened species in southern Australia. Aims

Asymbiotic germination of ornamental Vanda: in vitro germination and development of three hybrids
Plant Cell, Tissue and Organ Culture, 2007The majority of potted flowering orchids sold in the United States are Phalaenopsis hybrids. However, demand for other genera will undoubtedly increase as consumers become accustomed to growing orchids in the home. The objective of this study was to compare the germination and development of three Vanda hybrids, a genus with mass market potential ...

Effect of different media compositions on asymbiotic germination of Cymbidiums
Indian Journal of Forestry, 2009A protocol for seed germination and seedling culture of Cymbidium aloifolium (L.) Sw. and C. bicolor Lindl. Was developed. Green “matured” capsules containing seeds were surface sterilized and cultured on various media compositions. Murashige and Skoog (MS) medium with or without 10% coconut water (CW) promoted higher rate of initial seed germination ...

Comparative Transcriptome Analysis of Genes Involved in GA-GID1-DELLA Regulatory Module in Symbiotic and Asymbiotic Seed Germination of Anoectochilus roxburghii (Wall.) Lindl. (Orchidaceae) [PDF]
International Journal of Molecular Sciences, 2015 Anoectochilus roxburghii (Wall.) Lindl. (Orchidaceae) is an endangered medicinal plant in China, also called “King Medicine”. Due to lacking of sufficient nutrients in dust-like seeds, orchid species depend on mycorrhizal fungi for seed germination in ...

Use of Tomato Juice in the Asymbiotic Germination of Orchid Seeds
Botanical Gazette, 19491. Germination and growth data indicate that tomato-juice-agar solutions are more effective than the synthetic culture media containing only sugar and salts used generally for the asymbiotic germination of orchid seeds. These tomatojuice solutions are more strongly buffered in the pH range, 4.5-5.5, for good growth, even when the concentration of ...

In vitro asymbiotic germination and seedling development of Limodorum abortivum (Orchidaceae)
Plant Biosystems - An International Journal Dealing with all Aspects of Plant Biology, 2009Abstract Germination tests were carried out using immature seeds of Limodorum abortivum and applying in vitro techniques. The results proved that BM1 culture medium is suitable to promote both germination and further growth stages. Details of the developmental pattern, and some micromorphological features, are described.

Aim of study: Despite protection by international agreements, millions of orchid tubers are harvested from their natural distribution areas each year. Of these species, Himantoglossum robertianum is locally threatened due to overharvesting and requires precautionary measures to ensure its protection.
