Symbiotic seed germination and protocorm development of Aa achalensis Schltr., a terrestrial orchid endemic from Argentina

Aa achalensis is an endangered terrestrial orchid endemic from Argentina. In vitro symbiotic seed germination was evaluated for its propagation. Five different fungal strains were isolated from this species: two Rhizoctonia-like related to Thanatephorus cucumeris and three ascomicetaceous fungi belo...
