Microsatellite markers in the western prairie fringed orchid, Platanthera praeclara (Orchidaceae)1
UNLABELLED PREMISE OF THE STUDY Primers for 31 microsatellite-containing loci were developed for the threatened orchid Platanthera praeclara to enable characterization of the population genetics of this tallgrass prairie native. • METHODS AND RESULTS Sixteen polymorphic microsatellite loci were identified from four populations. Six of these loci were not in linkage disequilibrium. The aver...

متن کاملCharacterization of sympatric Platanthera bifolia and Platanthera chlorantha (Orchidaceae) populations with intermediate plants
Platanthera bifolia and P. chlorantha are terrestrial and rewarding orchids with a wide Eurasian distribution. Although genetically closely related, they exhibit significant morphological, phenological and ecological differences that maintain reproductive isolation between the species. However, where both species co-occur, individuals with intermediate phenotypic traits, often considered as hyb...
متن کاملSeed Germination of Gastrodia elata Using Symbiotic Fungi, Mycena osmundicola
The germination rate and longevity of seeds of Gastrodia elata Blume have been observed for 48 weeks using Mycena osmundicola strain H-21, one of fungi stimulating seed germination. Storage condition of post-harvest seeds was observed in the different temperature ranges of -30℃, -5℃, 5℃ and 30℃ for 48 weeks. After storage period of 48 weeks, the germination rate of G. elata was 65.7% at 5℃ and ...
متن کاملEx situ germination as a method for seed viability assessment in a peatland orchid, Platanthera blephariglottis.
UNLABELLED • PREMISE OF THE STUDY Assessing seed quality in orchids has been hindered by stringent germination requirements. Seed quality has traditionally been assessed in orchids using in vitro or in situ germination protocols or viability staining. However, these methods are not always well suited for rapid assessment of viability in the context of ecological studies.• METHODS The potent...
