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 pelotonisolated 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.

First published online: 13 September 2018. Licensed under a Creative Commons Attribution-NonCommercial-No Derivs 3.0 Costa Rica License. Introduction. Orchids form minute dust-like seeds that are ideal for wind dispersal. However, they are unable to store nutrients in the embryo and often rely on fungi (predominantly imperfect Rhizoctonia spp.) in order to germinate (Arditti & Ghani 2000, Brundrett et al. 2003, Rasmussen 1995). When fungi colonise orchid seeds, they grow as intracellular tightly coiled hyphal pelotons and a symbiotic relationship is established (Huynh et al. 2004). In this symbiotic relationship, fungi supply the orchid with nutrients including nitrogen (Girlanda et al. 2011) and phosphorus (Cameron et al. 2007) while the orchid supply carbon to the fungus (Cameron, Leake & Read 2006, Látalová & Baláž 2010). Carbon utilisation by mycorrhizal fungi vary with some clades from the same Rhizoctonia species inhibited by sucrose (Wright et al. 2011) resulting in suboptimal seed germination (Huynh et al. 2004, Nikabadi et al. 2014, Wright et al. 2009). Some in vitro studies have successfully germinated orchid seeds asymbiotically (without fungi) using specific stimulants such as growth hormones to promote germination (Huynh et al. 2004, Nikabadi et al. 2014). Despite the germination success of asymbiotic plants, symbiotically germinated orchids established in soil better in the long term than those without fungi (Batty et al. 2001, Rasmussen 1995) which suggests fungal superiority and importance to orchid conservation particularly for plants that reside in depleted nutrient habitats. Fungal specificity of orchids is highly variable between species and different fun","PeriodicalId":18023,"journal":{"name":"Lankesteriana","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42778528","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

His activities in Brazil from 1813 to 1830 are here described, a time during which his house in Rio and his famous fazenda Mandiocca became the center of scientific activity and the point of attraction for European travellers and naturalists who flocked to Brazil after its frontiers were opened to foreigners in 1808 by King Joao VI of Portugal. Wilhelm Freyreiss, Friedrich Sellow, Maximilian zu Wied-Neuwied, Augustin de Saint-Hilaire, Carl Friedrich Philipp von Martius, Johann Baptist von Spix, Giuseppe Raddi, Johann Baptist Emanuel Pohl, and Ludwig Riedel are among those who explored Brazil impulsed by von Langsdorff and often under his patronage. Their journeys in Brazil culminated in von Langsdorff’s ill-fated expedition to the interior of Brazil between 1822 and 1829, while the epilogue is marked by Langsdorff’s return to Germany, in a state of insanity and no longer able to publish the results of his life-long scientific efforts.","PeriodicalId":18023,"journal":{"name":"Lankesteriana","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44794862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
