Other claims from this paper (14)
- Observation Mycorrhizal associations of Australian Lobelioideae were complex.
- Observation Perennial species were solely VA mycorrhizal.
- Observation Annual species were both VA and ectomycorrhizal.
- Observation Three Lobelia species had unusual intercellular mycorrhizas with ectomycorrhizal ascomycetes.
- Observation Five Lobelia species from South Africa or North America were solely VA mycorrhizal regardless of life cycle.
- Observation Australian Lobelioideae seed required months of ripening before germination.
- Observation Seeds of L. gibbosa and L. simplicicaulis beside ascomycete mycorrhizas with Melaleuca uncinata germinated, grew and flowered.
- Observation The subterranean stage dependent on a mycorrhizal companion plant lasted 3-4 months.
- Observation Germinated L. gibbosa seed on simple agar did not become mycorrhizal or develop further.
- Observation In asymbiotic culture with sucrose, L. gibbosa seedling growth was slight.
- Intervention effect With sucrose and kinetin or N-benzylaminopurine, L. gibbosa developed shoots and small flowering plants.
- Observation L. gibbosa root development was scanty or absent even with two growth substances.
- Observation Field collected young L. gibbosa transplanted to U.C. mix or sterilised forest soil failed to produce new roots.
- Observation Transplanted L. gibbosa grew slowly, remained small and produced few flowers.
