SYMBIOTIC SEED GERMINATION OF AERIDES MULTIFLORA ROXB. – A STUDY IN VITRO
ORCHIDS ARE well known for their beautiful foliage and attractive flowers of varying shapes and sizes. They produce a large number of seeds, but less than one percent of these germinate under naturalExpand
In vitro germination, protocorm formation, and plantlet development of Orchis coriophora (Orchidaceae), a naturally growing orchid species in Turkey
TLDR
Orchimax medium including activated charcoal and supplemented with 0.25 mg/L 6-benzyladenine was found to be the most suitable medium for the formation of plantlets from protocorms, and the highest germination rate (44.2%) was observed in OrchimAX medium includingactivated charcoal plus 1mg/L indole-3-acetic acid.

The effect of orchid immature embryos age on asymbiotic germination frequency by optimizingplant growth regulators
Objective Orchids seeds are so small, lacking nutrients and barely germinate in natural condition. For germinating in natural conditions, should associatie with fungi, especially mycorrhizal fungi.Expand
An Overview on Orchid Endophytes
TLDR
Both the role such endophytes play and how such symbiotic partner scan be used in the plant tissue culture technique to help conserve and even commercialize various species of orchid are considered. Expand

TLDR
This chapter document the timing of seed collection and pretreatments for improving in vitro germination of some terrestrial Asian orchids. Expand
Functional Insights into the Roles of Hormones in the Dendrobium officinale-Tulasnella sp. Germinated Seed Symbiotic Association
TLDR
Dendrobium seed symbiotic germination may be stimulated by the apparent involvement of the OMF in the production of hormones, and relatively low concentrations of endogenous JA, ABA, or SLs might be maintained to promote the growth of the D. officinale-Tulasnella symbiotic protocorm-like body. Expand
Host tree specificity and seed germination of Dendrobium aphyllum (Roxb.) C.E.C. Fisch. in Sri Lanka
TLDR
The physical characteristics of bark such as texture, peeling behaviour and thickness showed a positive correlation with the host tree specificity of D. aphyllum, and the effect of host tree species on seed germination fluctuated with the concentration of host bark extracts. Expand
Effects of altering medium strength and sucrose concentration on in vitro germination and seedling growth of Cypripedium macranthos Sw
TLDR
It is demonstrated that the 1/4 MS medium, supplemented with 10 g·L -1 sucrose, could improve in vitro germination, and facilitate the growth of seedlings developed from the protocorms of C. macranthos Sw. Expand
Influence of mycorrhizal fungi on seed germination and growth in terrestrial and epiphytic orchids
TLDR
For the first time, the parallel ecological importance of mycorrhizal fungi in overcoming light inhibition of seed germination and growth in both terrestrial and epiphytic orchids is shown. Expand
History of orchid propagation: a mirror of the history of biotechnology
TLDR
This review traces the history of several techniques, additives, and peculiarities (agitated liquid cultures, coconut water, banana pulp, a patent and what appears to be an empty claim) which are associated with orchid micropropagation. Expand

The Sensitivity of Orchid Seedlings to Nutritional Ions
TLDR
A study on the sensitivity of germinating orchid seeds and young seedlings to different nutritional ions and the results are reported on the nutrition of different species of Odontoglossum. Expand
Physiological Study of the Symbiotic Germination of Orchid Seeds
TLDR
In two previous papers (6, 7), evidence that germination of orchid seeds is dependent upon an available supply of organic matter is presented and certain views with respect to the possible function of the fungus in the pure culture experiments are presented. Expand
The effect of sucrose and other factors on the shoot-root ration of orchid seedlings.
TLDR
It was noted in this laboratory that increased sugar content in the medium resulted in a marked effect on the growth pattern of orchid seedlings, and the following experiments were performed to ascertain whether a similar response could be obtained by other means. Expand
Nonsymbiotic Germination of Orchid Seeds
TLDR
The results thus far obtained indicate that the method is of value in the propagation of orchids from seeds, and the necessity of fungus infection for germination has not yet been proved. Expand
Effects of Vitamins on Germination and Growth of Orchids
TLDR
Good germination and excellent development of the seedlings occurred when nicotinic acid (P-P factor) was supplied in the nutrient medium and the presence of pyridoxine permitted good germination, but subsequent development was poor. Expand
Sources of Carbohydrate for Germination and Growth of Orchid Seedlings
Ever since 1840, when Linck observed the endophytic fungus in orchid roots, the symbiotic relationship between these interesting plants has been studied by mycologists, plant physiologists, andExpand
Non-symbiotic germination of orchids
TLDR
The authors' present knowledge of the requirements for successful germination of orchid seeds is derived from the experiments of Knudson and other investigators, and from the metabolic processes of the fungus bring about chemical changes in the medium which make it more assimilable. Expand
Further Observations on Nonsymbiotic Germination of Orchid Seeds
TLDR
While the method may be useful in the germination of Cattleya and related forms, it will not prove successful for the seeds of Odontoglossum and related genera. Expand
THE EFFECT OF NITROGEN ON THE GERMINATION OF VANILLA PLANIFOLIA
TLDR
The desirability of further investigation of vanilla seed dormancy and germination became apparent, and the study reported here was undertaken. Expand
