Germination in Seed Species Ingested by Opossums: Implications for Seed Dispersal and Forest Conservation
Seed germination in plant species consumed by opossums, genus Didelphis, was investigated in southern Brazil, in order to improve knowledge of the strategies of zoochorous plants in the Neotropics. Seeds were obtained from opossum feces. Thirteen of the most frequent species in the diet of local opossums were tested for germination rates and germination responses under different qualities (red/...
متن کاملHigh 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 کاملMycorrhizal Symbiosis in Aplectrum, Corallorhiza and Pinus.
When plants of different types are closely crowded together or anatomically engaged, in addition to the ensuing competitions, several special relations including immunities, antagonisms, toxicities, parasitism, or symbiosis may arise. A secretion by one plant which inhibits the growth of a neighboring organism, such as the substance found in the tissues of orchids by NOEL BERNARD which limits t...
متن کاملExpanding genomics of mycorrhizal symbiosis
The mycorrhizal symbiosis between soil fungi and plant roots is a ubiquitous mutualism that plays key roles in plant nutrition, soil health, and carbon cycling. The symbiosis evolved repeatedly and independently as multiple morphotypes [e.g., arbuscular mycorrhizae (AM), ectomycorrhizal (ECM)] in multiple fungal clades (e.g., phyla Glomeromycota, Ascomycota, Basidiomycota). The accessibility an...
