the chlorophyll-containing orchid corallorhiza trifida derives little carbon through photosynthesis.	while measurements of tissue stable isotope signatures and isotope mixing models have suggested that the green orchid corallorhiza trifida is photosynthetically active and hence only partially mycoheterotrophic, these assumptions have not been validated by direct analysis of carbon assimilation. the photosynthetic capabilities of three orchid species assumed on the basis of the indirect methods or chlorophyll content to have differing trophic strategies: neottia nidus-avis (fully mycoheterotroph ...	2009	19402877
the ectomycorrhizal specialist orchid corallorhiza trifida is a partial myco-heterotroph.	the leafless, circumboreal orchid corallorhiza trifida is often assumed to be fully myco-heterotrophic despite contrary evidence concerning its ability to photosynthesize. here, its level of myco-heterotrophy is assessed by analysing the natural abundance of the stable nitrogen and carbon isotopes (15)n and (13)c, respectively. the mycorrhizal associates and chlorophyll contents of c. trifida were investigated and the c and n isotope signatures of nine c. trifida individuals from central europe ...	2008	18221248
