In this study, the effect of smoke derivatives and carbon utilisation was explored to improve germination and seedling establishment of an Australian endangered orchid, Pterostylis despectans (Lowly Greenhood) and its mycorrhizal fungi. Stored seeds were germinated in vitro with peloton- isolated fungal isolates with varying concentrations of smoke water (0-1.0 mL L-1) to simulate fire and sucrose as the carbon source (10 g L-1). Smoke water significantly increased germination, with advanced protocorms and robust seedlings produced. Sucrose inhibited germination such that protocorms and leafing was absent with sucrose inclusion. Fungal isolates were highly variable on its germination efficacy and tolerance to smoke water, highlighting the importance of fungal diversity and supports research-based conservation strategies to circumvent environmental challenges. 2018 artículo científico 1409-3871 https://www.redalyc.org/articulo.oa?id=44359783002 https://www.redalyc.org/journal/443/44359783002/ https://www.redalyc.org/journal/443/44359783002/html/ https://www.redalyc.org/journal/443/44359783002/44359783002.epub https://www.redalyc.org/journal/443/44359783002/movil 10.15517/lank.v18i3.34534 en http://www.redalyc.org/revista.oa?id=443 Lankesteriana International Journal on Orchidology application/pdf Universidad de Costa Rica Lankesteriana International Journal on Orchidology (Costa Rica) Num.3 Vol.18 |
