Abstract

The biological function ofLentinula edodes in a myco-heterotrophic orchid,Erythrorchis ochobiensis was examined, using one local variant each from Japan (JPN), Papua New Guinea (PNG) and New Zealand (NZ). All variants induced seed germination: PNG and NZ isolates were effective at 25°C and JPN isolate showed the highest germination rate at 30°C. Germinated seeds developed into plants and formed normal endomycorrhizas. Hence, it is concluded thatL. edodes has a perfect symbiotic potential withE. ochobiensis, though it has not been observed in the root of the orchid in the field.
