Abstract

|
Mycorrhizal fungi (Rhizoctonia spp.) were isolated from the roots and rhizomes of Cymbidium goeringii collected from Kwangju and Tamyang. The results of the experiments on mycorrhizal fungi are summarized as follows. Active mycorrhizal fungi observed under scanning electron microscope were on the surface and in the cortical cells of the roots and rhizomes, and a number of undigested or partially digested peloton in the cortical cells of the rhizomes. Rhizoctonia repens group (KR 002, KR 003) and Rhizoctonia spp. (KR 001) were isolated from the roots and rhizomes of C. goeringii in Kwangju and Tamyang. In the back-inoculation test of Rhizoctonia spp., the infection of rhizomes formed by tissue culture were observed. Effects of Rhizoctonia spp.(KR 001, 002, 003) on the germination test of mature seeds were investigated on oat-meal agar. The promotion of germination was observed only in Rhizoctonia repens (KR 003).
