High specificity generally characterizes mycorrhizal association in rare lady's slipper orchids, genus Cypripedium.
Lady's slipper orchids (Cypripedium spp.) are rare terrestrial plants that grow throughout the temperate Northern Hemisphere. Like all orchids, they require mycorrhizal fungi for germination and seedling nutrition. The nutritional relationships of adult Cypripedium mycorrhizae are unclear; however, Cypripedium distribution may be limited by mycorrhizal specificity, whether this specificity occu...

متن کاملLife History Trade-offs in a Rare Orchid: the Costs of Flowering, Dormancy, and Sprouting
We tested for life history trade-offs among dormancy, sprouting, and flowering in a seven-year study of a threatened, perennial plant, the small yellow lady’s slipper orchid (Cypripedium calceolus ssp. parviflorum (Salisb.) Fernald). The aboveground states of 629 genets were monitored over seven years in a wet meadow in northeastern Illinois, USA. With mark–recapture statistics, survival, resig...
متن کاملEmbryo development in the lady's slipper orchid, Paphiopedilum delenatii, with emphasis on the ultrastructure of the suspensor.
BACKGROUND AND AIMS Owing to large-scale collecting, the lady's slipper orchid, Paphiopedilum delenatii, is under threat of extinction. Asymbiotic germination provides a useful way to re-establish plants in the wild and for commercial propagation. A detailed study of embryo development would provide information on subsequent germination events and aid in the propagation of the species. METHOD...
