cephalanthera falcata/クロロフィル

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

• Achlorophyllous variants of some forest orchids are known to reach almost the same size as their green forms. These vegetative albino forms cover their entire carbon (C) demand through fungi that simultaneously form ectomycorrhizae with trees, while green variants partially draw on C from
