TLDR
Investigating the biology of the early life history and size of seed/seedling populations relative to the number of plants that eventually emerge above ground in orchid seeds finds considerable variation in germination strategies, patterns of seedling development and establishment, substrate requirements, and levels of specificity with the fungi.About:

Ecology of woodland herbs in temperate deciduous forests
TL;DR: The literature on the ecology of woodland herbs is reviewed because a number of species have become rare or threatened owing to the conversion of forests to other land uses, competition by alien plant species, and increased abundance of native wildlife that negatively impact woodland herbs.

Recent developments in the study of orchid mycorrhiza
TL;DR: There is an increasing evidence of specific relationships between orchids and fungi, though usually not on a species-to-species level, and Physiological compatibility demonstrated under artificial conditions, as in vitro, may be much broader, however.
Journal ArticleDOI
Constraints to symbiotic germination of terrestrial orchid seed in a mediterranean bushland.
TL;DR: The measurement of the spatial variability in germination events within an orchid habitat demonstrated the availability of new recruitment sites and was required to assess the natural recruitment capacity and the potential for orchid reintroduction in natural habitats.
Journal ArticleDOI
What constrains the distribution of orchid populations
TL;DR: A broader investigation of orchid mycorrhizal fungus distribution in the soil, coupled with fungus and recruitment mapping, is needed to translate fungal abundance to orchid population dynamics and may lead to better orchid conservation.
Book ChapterDOI
Mycorrhizal Specificity and Function in Myco-heterotrophic Plants
TL;DR: It is argued that specificity represents a continuum and can only be properly assessed using phylogenetic data, and whether myco-heterotrophic orchids interact with fungi in fundamentally different ways than do autotrophs.

Seed ecology of dust seeds in situ: a new study technique and its application in terrestrial orchids
TL;DR: For the first time it is possible to conduct a quantitative study of orchid germination in situ and observe seasonal growth and mortality of seedlings and the relation between the site where the seeds are sown, the availability of an appropriate fungus to infect the seeds, and seedling establishment in the soil.

In vitro germination of some Western European orchids
J. M. Van Waes,P. C. Debergh +1 more
TL;DR: Experiments with 3 species have shown that the objective, to obtain a germination percentage, which approximated the maximum percentage of coloured embryos, was achieved, and this has led to the elaboration of a basic sowing method for European orchids.

In situ and in vitro specificity between Rhizoctonia spp. and Spiranthes sinensis (Persoon) Ames. var. amoena (M. Bieberstein) Hara (Orchidaceae)
Gaku Masuhara,Keizo Katsuya +1 more
TL;DR: The relationship between the orchid Spiranthes sinensis (Persoon) Ames var. amoena and fungi in situ conditions was investigated in situ at germination and in adult plants as discussed by the authors.

The Natural Forests of Maryland: An Explanation of the Vegetation Map of Maryland
TL;DR: The forests of Maryland have been mapped at a scale of 1:250 000 on the basis of 15 regional associations: tamarack, bald cypress, hemlock, yellow birch-black birch, (4) river birch--sycamore, (5) sycamore-green ash-box elder-silver maple, (6) shingle oak, (7) chestnut oak-post oak-blackjack oak,(8) Chestnut Oak, (10) loblolly pine, (11) basket oak-loblolly pine),
