Carbon nutrition of mature green orchid Serapias strictiflora and its mycorrhizal fungus Epulorhiza sp.
Original language description
We studied the nutritional modes of the S. strictiflora and Epulorhiza sp. using the differences in carbon isotopic composition (delta C-13) of C-3 orchid and C-4 maize tissues. We found that if cultivated in substrate lacking any organic compounds, theextraradical mycelia (delta C13=-26.3) developed well, despite being fully dependent on nutrition from orchid roots (delta C13 =-28.6). If the fungus had additional access to and colonized decaying maize roots (delta C13=-14.6), its isotopic composition(delta C13=-21.6) reflected a mixture of biotrophy and saprotrophy. No statistically significant differences in delta C-13 of new storage tubers were found between Epulorhiza-associated orchids with (delta C13=-28.2) and without access to maize roots (delta C13=-28.6). We conclude that autotrophy is the predominant nutritional mode of mature S.
