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.

Asymbiotic seed germination of hand-pollinated terrestrial orchids
Acta Horticulturae, 2017Orchids are known for their adaptation to different environmental and biotic factors, especially pollinators and mycorrhizal fungi. Association with symbiotic fungi has a crucial impact on orchid growth and metabolism, from germination through the seedling stage and in many cases throughout their life.

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 ...

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 ...

Asymbiotic Germination and Seedling Development of Dimorphics lowii (Orchidaceae)
Asian Journal of Plant Biology, 2014Dimorphorchis lowii, a threatened Borneo endemic epiphytic orchid, is gradually becoming rare due to over collecting and habitat disturbance. Therefore this study was carried out to obtain in vitro propagation through asymbiotic seed germination and seedling development by optimizing capsule maturity, nutrients requirements and light conditions before ...

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.

Abstract The Insubric bee orchid, Ophrys benacensis (Reisigl) O.E p = 0.024, Student’s t‐test), whereas other complex organic media inhibited germination. We conclude that both pollen and ovules have inherent developmental problems that can be partially overcome by outbreeding with larger populations.

Asymbiotic germination of Odontoglossum gloriosum RCHB.F (Orchidaceae) under in vitro conditions
In Vitro Cellular & Developmental Biology - Plant, 2006An efficient seed germination system was developed for an endemic and endangered orchid of the prairies of Bogota, Colombia. The effects of three culture media [Murashige and Skoog (MS) salts (1962); Knudson C (KC) salts (1946); and Hydro-Coljap® salts], activated charcoal [0 and 0.5% (w/v)], α-naphthaleneacetic acid (NAA; 0.0, 2.68 and 5.37 μM), and ...

EFFECT OF MEDIUM COMPOSITION ON ASYMBIOTIC SEED GERMINATION OF FIVE PHALAENOPSIS SPECIES
Acta Horticulturae, 2010Phalaenopsis has become one of the most important flowering potted plants in the world. In order to create novel flower colors and types, various species have been introduced in breeding programs. For the conservation and sustainable utilization of the germplasm, here, we investigated the effect of medium composition on the asymbiotic germination and ...
